Question

evaluate the function f(x)=9x+1
of the given values of the independent variables and simplify

a) f(-5)
b) f(x-5)
c) f(-x)

Answer 1

i think I have a and b done
a) would be -44
b) would be 9x+45

Answer 2

A is correct! and B is sooo close! you forgot about the +1

Answer 3

and that it's -5

Answer 4

f(x-5) = 9(x-5)+1
= 9x -45+1
do the last step


f(-x) = 9(-x) +1

= -9x+1
