Question

Given the following functions, find the indicated values.
f(x)= 7 - 9x
(a) f(-9) (b) f(0) (c) f(2)
(a) f(-9)=

Answer 1

Answer:

a = 88, b = 7, c = -11

Step-by-step explanation:

a)

f(x) = 7 - 9x

f(-9) = 7 - 9(-9)

f(-9) = 7 + 81

f(-9) = 88

b)

f(x) = 7 - 9x

f(0) = 7 - 9(0)

f(0) = 7

c)

f(x) = 7 - 9x

f(2) = 7 - 9(2)

f(2) = 7 - 18

f(2) = -11
