f(x)=x^2-1 ; x = -3, -2, -1, 0, 1, 2, 3

i got 8,3,0,-1,0,3,8 as the answer when i plugged in x. how would i graph these numbers from this function?

  • Algebra -

    just plot the points for the y-values you found:

    (-3,8)
    (-2,3)
    and so on

    It should look like a parabola with its vertex at (0,-1)

    f(2)=5 f(-2)=1, I have to write the linear function for this. I got 5-1/2- -2=4/4=1 then I plugged it in so it would be y-5=1(x+2) which became y=x+7, then f(x)=x+7. The answer key, however, says f(x)=x+3. What did I do wrong?
