Joyce Bean · Answer 1

zeroes: x = - 9 and x = - 7

Step-by-step 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!
