Best ResponseYou've already chosen the best response.0Possible answers: Function A is described by the graph below. Function B is defined by the equation y = log2 x. Choose all the statements below that are true. There is more than one correct answer; be sure to choose all the correct answers. Function A has a greater value than function B when x ≤ 1. Neither function has a yintercept. Both functions increase as x increases. Both functions have the same yintercept, at y = 0. Both functions have the same xintercept, at x = 1. Function B has a greater value than function A when x ≤ 1. Both functions decrease as x increases.

Best ResponseYou've already chosen the best response.1Not sure I know the answers for this one, but the function B copy and pasted a little strangely is it supposed to look like this? \[\log_2{x}\]

Best ResponseYou've already chosen the best response.0@jtvatsim the way it's copy and pasted here is how it looks on my assignment

Best ResponseYou've already chosen the best response.1with the little square box thing? That must have just been a mistake on the assignment then. No worries.

Best ResponseYou've already chosen the best response.0@jtvatsim I think so, but can you help >.< I'm so confused

Best ResponseYou've already chosen the best response.1I'm looking right now. You will need to be familiar with what this equation means \[y = \log_2{x}\] have you studied logarithms in your class?

Best ResponseYou've already chosen the best response.0Yes, I've learned that.

Best ResponseYou've already chosen the best response.1OK, well I would recommend that we plot a short graph of Function B so that we will be able to answer the questions. All of the questions have to do with comparing the graphs. :)

Best ResponseYou've already chosen the best response.1I'm going to use desmos.com to get a graph for this part.

Best ResponseYou've already chosen the best response.1Here is the graph of Function B. Take a look! :)

Best ResponseYou've already chosen the best response.1So, a short way for us to remember which graph is which: Function A starts high and goes lower. Function B starts low and goes higher.

Best ResponseYou've already chosen the best response.1So, now for that first question: "Function A has a greater value than Function B when x <= 1" What do you think? Does that match our graphs?

Best ResponseYou've already chosen the best response.0No, aren't they equal when x <= 1

Best ResponseYou've already chosen the best response.0Oh wait, no! Lol it's true... right

Best ResponseYou've already chosen the best response.1Yes, it is true! Remember function A starts out high and function B starts out low. So clearly A has a greater value than B at first! :)

Best ResponseYou've already chosen the best response.0Okay lol. I only looked at the x when it met 1

Best ResponseYou've already chosen the best response.1Right, they are exactly the same when x = 1. But not when x < 1. Good job on #1 ! :)

Best ResponseYou've already chosen the best response.1What do you think about question #2? "Neither function has a yintercept" This one is a little tricky. But, I think you can do it! :)

Best ResponseYou've already chosen the best response.0false because graph A is on the y.. right?

jtvatsim

Best ResponseYou've already chosen the best response.1Right? This one is a bit debatable. But I think they want us to say true. Here's why...

jtvatsim

Best ResponseYou've already chosen the best response.1I think they are trying to show that Function A has a vertical asymptote at the yaxis. So it gets closer and closer, but never actually touches. You can answer it however you want. But, personally, I think they want us to say True neither graph touches. :)

Best ResponseYou've already chosen the best response.0It touches at the top doesn't it?

jtvatsim

Best ResponseYou've already chosen the best response.1On the graph it really does look like it. But (and this is just my experience) I've never seen a math question that has that shape and is supposed to touch the yaxis. I think it's a bad drawing, but again, answer it the way you feel most confident. This one is debatable, but I see your point as well. :)

Best ResponseYou've already chosen the best response.1Moving on! Question #3 is not debatable and much more clear: "Both function increase as x increases." Hmmm...

jtvatsim

Best ResponseYou've already chosen the best response.1Yep! Function A is definitely not increasing.

Best ResponseYou've already chosen the best response.1How about #4 "Both functions have the same yintercept at y = 0"? Hmm....

jtvatsim

Best ResponseYou've already chosen the best response.1Yep, even if we don't agree whether the graphs actually intercept the yaxis or not, if they do they are definitely not the same. Good!

Best ResponseYou've already chosen the best response.1How about #5 "the same xintercept at x = 1"?

jtvatsim

Best ResponseYou've already chosen the best response.1#6 "Function B greater than Function A when x <= 1"?

Best ResponseYou've already chosen the best response.0The last two are false, right?

jtvatsim

Best ResponseYou've already chosen the best response.1I'd say, Yes! You are right.
