Question

1. Use the pair of functions given to find the value of each of the following combination of functions.

f(x) = √x-3, g(x) = 5x + 15
(9-f)(4) =?

Answer 1

Answer: 34

Step-By-Step Explanation :

(5x+15)-/x-3

(5(4)+15)-/(4)-3 = 34

You basically change the ‘g’ and ‘f’ with the formula then blug in the 4

(g-f) —>formula

(4)—> change the ‘x’ to 4
