Question

Let f(x) = 2x – 1 and g(x) = 3x Find f(g(- 3))

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

f(x) = 2x – 1

g(x) = 3x

f(g(- 3))​ = ?

Step 02:

f(g(x)) = 2(3x) - 1

= 6x - 1

f(g(- 3))​ = 6(-3) - 1

= -18 - 1

= -19

The answer is:

f(g(- 3))​ = -19
