Question

What is the answer to this question plss and thank you

Answer 1

A defines the function

f(1) = - 8 ×(
`(5)/(2) )^(0)` = - 8 × 1 = -8

f(2) = - 8 ×(
`(5)/(2)) ^(1)` = -
`((8.5))/(2)`= - 20

f(3) = - 8 ×(
`(5)/(2)) ^(2)` = - 8 ×
`(25)/(4)` = - 50

f(4)= - 8 ×(
`(5)/(2)) ^(3)` = - 8 ×
`(125)/(8)` = -125

f(5) = - 8 ×(
`(5)/(2)) ^(4)` = - 8 ×
`(625)/(16)` = -
`(625)/(2)`
