Answer 2

The composite function (f + g)(x) is (f + g)(x) = 3x³ - 2x² + 10x - 12

How to evaluate the composite function

From the question, we have the following parameters that can be used in our computation:

f(x) = 3x³ - 2x² + 4x - 5

Also, we have

g(x) = 6x - 7

The composite function (f + g)(x) is calculated using

(f + g)(x) = f(x) + g(x)

Substitute the known values into the equation

(f + g)(x) = 3x³ - 2x² + 4x - 5 + 6x - 7

Evaluate

(f + g)(x) = 3x³ - 2x² + 10x - 12

hence, the composite function is (f + g)(x) = 3x³ - 2x² + 10x - 12
