Question

For all numbers x, the function f is defined by f(x) = 3x + 1 and the function g is defined by g(x) = x - (1/3). If c is a positive number, what is the value of g(c)? (1) f(c) = 13

Answer 1

11/3

Explanation:

f(c) =13

This means we need to calculate the actual value of c . We replace c with x in f(x)

13 = 3c + 1

3c = 12

c = 4

We put this value in g(x)

g(c) = g(4) = 4 - 1/3 = 11/3
