If f (x) = 3x² + 1 and g (x) = 1 - X, what is the value of (f - 9) (2) ?

(f - g) (2) = 14

Step-by-step explanation:

You can write the expression for the composite function as ...

(f - g) (x) = f (x) - g (x) = (3x² + 1) - (1 - x)

(f - g) (x) = 3x² + x

Then for x = 2 ...

(f - g) (2) = 3 (2²) + 2

(f - g) (2) = 14
