Question

Find the zeros of the function. Write the smaller solution first, and the larger solution second. f(x)=(x+8)^2−1

Answer 1

zeroes: x = -9 and x = -7

Explanation:

f(x)=(x+8)^2−1

A "zero" refers to when the y-value on the graph is zero.

0 = (x+8)^2 - 1

1 = (x+8)^2

+ or - 1 = x+8

so break them apart into two equations

x+8 = 1 OR x+8 = -1

x = -7 OR x = -9

You can plug both back in to check that the equation works!
