Best ResponseYou've already chosen the best response.1they're all quadratic, correct?

Best ResponseYou've already chosen the best response.1The steps are supposed to be described in words, i believe.

Best ResponseYou've already chosen the best response.1depends on what kind of resolution or general shape you need

Best ResponseYou've already chosen the best response.1they are all quadratic, you can put them in y = ax^2 + bx + c form

Best ResponseYou've already chosen the best response.1most important values to graph, Vertex xintercept if any yintercepts if any

Best ResponseYou've already chosen the best response.1@DanJS , @hwyl i don't think i can say the same answer for all of them though

Best ResponseYou've already chosen the best response.1start with one of them, and explain and show how to get a basic graph

Best ResponseYou've already chosen the best response.1f(x) = x^2 + 34 vertex x = b/(2*a) = 0/2 = 0 y=f(0) = 34 Vertex is at (x,y) = (0,34)

Best ResponseYou've already chosen the best response.1okay so like for example with part a) Find the vertex, create a table of values, and graph them?

Best ResponseYou've already chosen the best response.1the sin on the coefficient of the squarred term is negative, and tells you the parabola opens down...there will be xintercepts xintercepts are where y=0,, solve y = 0 = x^2 + 34 plot the points (x,0)

Best ResponseYou've already chosen the best response.1It's just that i feel like the same steps are followed for the every question. So, i don't understand how you're supposed to find the steps for each one to differentiate in words

Best ResponseYou've already chosen the best response.1yeah, i would find the vertex first, then find the x and y axis intercepts if they exist

Best ResponseYou've already chosen the best response.1you can use numbers to, just explain what you are doing, and show the graph of each point you find

Best ResponseYou've already chosen the best response.1You can list the values in a table if you want, but not really needed

Best ResponseYou've already chosen the best response.1You can draw all that from just finding the vertex (0,34)

Best ResponseYou've already chosen the best response.1and knowing that the negative on the x^2 term means it opens down

Best ResponseYou've already chosen the best response.1then find the values where the function crosses the x axis +a and a points (+a , 0) and (a , 0) Those are the x intercepts found by solving y = f(x) = 0 = x^2 + 34

Best ResponseYou've already chosen the best response.1That's how the question is set up on my paper. ^^^ The question in its function notation with two lines underneath

Best ResponseYou've already chosen the best response.1every question is set up like that so there's no room to graph or anything like that

Best ResponseYou've already chosen the best response.1ok, just explaine however you need to how you would make a graph of that function

Best ResponseYou've already chosen the best response.1if it is blank paper, i would assume you can draw and show equations as long as you back it up with a worded explination

Best ResponseYou've already chosen the best response.1" the function is this, , this is how you find the vertex point, , this is how you determine the direction of the parabola, this is how you find the axis intercepts if they exist for the function "

Best ResponseYou've already chosen the best response.1@DanJS ahhh okay that makes more sense now. Thank you!

Best ResponseYou've already chosen the best response.1if you want more detail you can pick any x value and solve for the corresponding y value, and add as many random points you want and build a table

Best ResponseYou've already chosen the best response.1welcome, i think they just want the important points, so you can get a basic graph
