Question

Given f(x) = –x + 6 write an equation for f(x + 3). f(x + 3) f(x+3)=______x_____ _____the first and third blank has to be either 3,9.-1 or 1. the second blank has to be a add subtract or multiply sign

Answer 1

Its a function composed, with other function y=x+3

Then

f(x+3) = - (x+3) + 6

f(x+3) = -x -3 + 6 = -x + 3.

then answer is -1, add sign, 3
