Select the correct answer. If f (x) = x^1/2-x and g (x) = 2x^3-x^1/2-x, find f (x) - g (x).

(f-g) (x) = 2√x - 2x³

Step-by-step explanation:

Write out the terms of f (x) as they are and then the negatives of all the terms of g. We get:

(f-g) (x) = √x - x - 2x³ + √x + x

Combining like terms, we get:

(f-g) (x) = 2√x - 2x³
