Find f\left(x+3\right)f(x+3) given the function: f\left(x\right)=-5x+3f(x)=−5x+3
Serjik [45]

Answer:

-5x-12

Step-by-step explanation:

Given f(x) = -5x+3, to get f(x+3), we are going to replace x in f(x) with x+3 as shown;

f(x) = -5x+3

f(x+3) = -5(x+3)+3

f(x+3) = -5x-15+3

f(x+3) = -5x-12

Hence the function f(x+3) is -5x-12
