Question

how would I graph y=f(x)

Answer 1

??

Answer 2

what is f(x)?

Answer 3

You sure that is the question?

Answer 4

yes its said to graph this y=f(x)

Answer 6

I don't understand what Wolfram says. :/

Answer 7

well f(x) is going to be some function of x. lets assume that function is just x. There for y=x. You can solve this and say that x-y=0. This might be a plane, but i'm not entirely sure.

Answer 8

No, it's a line. Never mind. i would ignore wolfram alpha on this one. My guess is that it's wanting you to describe how you would go about graphing something like this.

Answer 9

yes graphing it

Answer 10

You graph things by plugging in x, solving for your f(x) and getting an answer which is your y.

Lets assume f(x)= 3x-2.
x=0, then y=3(0)-2 = -2.
x=1, then y=3(1)-2 = 1
x=2, then y=3(2)-2 = 6-2 = 4.

etc, etc.. Does that make sense?

Answer 11

how would i graph it

Answer 12

Well here we now know that when
x=0, y=-2
x=1, y=1
x=2, y=4

Then take some graphing paper, or grid paper. the x-axis goes from left to right, the y-axis goes from top to bottom. Where the two intersect is called the origin and is x=0 and y=0 or written like (0,0).

Then just count the lines and what not and place the points where they should be.
