Question

If f (x) = 2 + x and g(x) = 3 - X, what is gof(-1) ?206-4

Answer 1

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

Step 01:

Data

f (x) = 2 + x

g(x) = 3 - x

gof(-1) = ?

Step 02:

gof(x) = 3 - (2 + x)

= 3 - 2 - x

= 1 - x

gof(-1) = 1 - (-1)

= 1 + 1

= 2

The answer is:

gof(-1) = 2
