Best ResponseYou've already chosen the best response.0C is correct...you can always think of it as a x,y chart if that helps.

Best ResponseYou've already chosen the best response.1fast way to know this is to input 0 into both equation to see its output so...

Best ResponseYou've already chosen the best response.1when input 0 into function 1 we get f(0)=1 while g(0)=2 ....

Best ResponseYou've already chosen the best response.0sorry, I was distracted...go back to the last problem please. with the 2 function, I disagree with A

Best ResponseYou've already chosen the best response.1how can it be B when they didnt give the x value of x=2 for g(x)?

Best ResponseYou've already chosen the best response.0ok, so looking at the chart I like to think of it as x,y instead of x, g(x). Based on the data given in the table, g(x) has a vertex at 1, 3, because x=2 and x=0 have the same g(x) value. So the low point for g(x) is the vertex 1, 3

Best ResponseYou've already chosen the best response.1\[f(x)=2(x)^{2}8(x)+1\]when x=2 f(2)=25 and g(x)=2 for the g(x) part they didnt give the function but they state the function output for the given value of x...thats how i see that question...

Best ResponseYou've already chosen the best response.0Water coming out from a fountain is modeled by the function f(x) = −x2 + 8x + 2 where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds. What does the average rate of change of f(x) from x = 1 to x = 4 represent? a. The water travels an average distance of 3 feet from 1 second to 4 seconds. b. The water travels an average distance of 2 feet from 1 second to 4 seconds. c. The water rises up with an average speed of 3 feet per second from 1 second to 4 seconds. d. The water rises up with an average speed of 2 feet per second from 1 second to 4 seconds.

Best ResponseYou've already chosen the best response.0@LynFran it's really hard to explain on here, but here's my terrible drawing of g(x)...when you graph it, you can clearly see that 1,3 is the vertex of the parabola....dw:1439742811899:dw

Best ResponseYou've already chosen the best response.0well, maybe not clearly from my drawing, but draw it yourself on paper and you'll see :)

Best ResponseYou've already chosen the best response.0@pflorido , for the actual question you're asking, I'd say you can cross off c and d, because they're talking about speed and it says in the problem that f(x) is the height of the water

Best ResponseYou've already chosen the best response.0now just plug in value so you can calculate the rate of change....so what's f(1) and f(4). Once you know those values, you can use them to find rate of change.

Best ResponseYou've already chosen the best response.0f(1) is 9 and f(4) is 18

Best ResponseYou've already chosen the best response.0actually, hold on I'm rereading the question and I'm not sure we can completely discount c and d yet! but still find the rate of change!

anonymous

Best ResponseYou've already chosen the best response.0yes, f(1) and f(4) are correct, so now find the rate of change \[\frac{ yy_{1}}{xx_{1}}\]

Best ResponseYou've already chosen the best response.0So the coordinates would be (9,0) and (0,18)... I am a little confused @stacy.reed08

anonymous

Best ResponseYou've already chosen the best response.0nope, you're coordinates are 1,f(1) and 4,f(4)....in other words (1,9) and (4,18)

Best ResponseYou've already chosen the best response.0looking at the rate of change equation, I realize I was definitely wrong at first! The yvalues , or f(x), represent height, while the xvalues represent time so the rate of change is literally distance divided by time...speed :)

Best ResponseYou've already chosen the best response.0So the rate of change is 9/3 or 3

anonymous

Best ResponseYou've already chosen the best response.0yes, or still think of it as 3/1...since rate of change is a ratio....3 feet for every 1 second.

Best ResponseYou've already chosen the best response.0The function f(x) = −x2 + 48x − 432 models the profit, in dollars, a game developer makes for selling a new game, where x is the number of games sold and f(x) is the amount of profit. Part A: Determine the vertex. What does this calculation mean in the context of the problem?  I know that the vertex is (24,144).... Part B: Determine the xintercepts. What do these values mean in the context of the problem? I know the xintercepts are (12,0) and (36,0)

anonymous

Best ResponseYou've already chosen the best response.0This equation is a parabola facing down, so the vertex would be the maximum profit that could be made.

anonymous

Best ResponseYou've already chosen the best response.0Oh ok and the xintercepts would be the prices when the profit is at zero, right?
