Question

Given f(x)=10x+5 and g(x)=3x+6 then what is (f+g)(−1)) ?

Answer 1

Answer:

-13x-11

Step-by-step explanation:

The function f(x) plus the other function g(x) is just another way of saying (10x+5)+(3x+6) which would give you 13x + 11. The next part is asking you to multiply 13x+11 by -1 which would give you the answer -13x - 11
