Question

Sketch the graph of the equation.
y = 3x^2 − 5
Label the x- and y-intercepts. (If an answer does not exist, enter DNE.)

Answer 1

Your y-intercept is going to be where x = 0.
Your x-intercept(s) will be the solution where y = 0, solve for x.

Answer 2

i know the y intercept is 0, -5

Answer 3

Okay, now you can set the equation equal to zero and solve for x. And those will be your x-intercepts.

Answer 4

im having trouble graphing it

Answer 5

i have x= +/- radical 5/3

Answer 6

That's precisely correct, now just put them together.
