Question

For the following function, determine the value of:

f(x)= -7x-7
f(-3)=
f(0)=
f(5)=
f(x-2)=

Answer 1

f(-3) = -7(-3) - 7

= 21 - 7 = 14

f(0) = -7(0) -7

= 0 -7 = (-7)

f(5) = -7(5)-7

= (-35) - 7 = (-42)

f(x-2) = -7(x-2) -7

= (-7x) + 14 - 7

7x = 7

x = 1

The bold one is the answer. Im sorry if my answer is wrong
