Question

What is the answer to this question plss and thank you

Answer 1

A defines the function

f(1) = - 8 ×( $\frac{5}{2} )^{0}$ = - 8 × 1 = -8

f(2) = - 8 ×( $\frac{5}{2}) ^{1}$ = - $\frac{(8.5)}{2}$= - 20

f(3) = - 8 ×( $\frac{5}{2}) ^{2}$ = - 8 × $\frac{25}{4}$ = - 50

f(4)= - 8 ×( $\frac{5}{2}) ^{3}$ = - 8 × $\frac{125}{8}$ = -125

f(5) = - 8 ×( $\frac{5}{2}) ^{4}$ = - 8 × $\frac{625}{16}$ = - $\frac{625}{2}$
