Question

What is the value of f[g(3)] for the functions f(x) = x + 3 and g(x) = 2x + 1? (Type only the value of your final answer, no variables.)

Answer 1

The answer is 10 work from inside

Answer 2

10

Explanation:

Work from the inside out.

g(3)= plug 3 in for x in the function g

g(3)= 2·3 + 1 = 6 +1 = 7

f(7) = plug 7 in for x in the function f.

f(7) = 7 + 3 = 10
