Question

help, please! i cannot figure out how to do the x-intercepts. i'm very unsure on how to figure those out.

Answer 1

Explanation:

To find the x-intercepts, find x when f(x) = 0

f(x) = x² + 2x - 2 = 0

Use the quadratic formula to find the 2 solutions for x (a=1, b=2, c=-2)

x = -1 ± √3

x = -2.732

x = 0.733

In other words, the graph intersects the x axis at these 2 points:

(-2.732, 0) and (0.7321, 0)
