Answer:
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!

Step-by-step explanation:
Working backwards:
17-3=14
14/2=7
7 is the second term in the sequence. Continue backwards.
7-3=4
4/2=2
2 is the first term in the sequence, aka your answer.
