Consider the function represented by the table.
for which x is f(x)? =–3
–7
–4
4
5
x i f(x)
-7 i -3
-3 i 5
2 i -4
4 i -8

f(-7) = -3

Step-by-step explanation:

From the table we have f(-7) = -3

Iknow one of the answers is a and maybe b but not 100% sure about b

Part a)  product a is decreasing by 18% per year1 - .18 = .82part b)  which product recorded a greater percentage change in price over the previous year?   product b recorded a greater percentage change.  justify your answer: the equation for product b is  y= 10000(.56)^x , and 1 - .44 = .56product b decreases by 44% per year
