Antony Peck · Answer 1

(hk) (x) = 2x³-18x

(k/f) (x) = 2

(h/g) (x) = x+3

Step-by-step explanation:

(hk) (x)

(x² - 9) (2x)

2x³ - 18x

(k/f) (x)

2x/x

2

(h/g) (x)

(x² - 9) / (x - 3)

[x² - 3²] / (x - 3)

(x + 3) (x - 3) / (x - 3)

x + 3

Use these functions to evaluate the following problems: f (x) = x, g (x) = x - 3, h (x) = x^2 - 9, k (x) = 2x(hk) (x)(k/f) (x)(h/g) (x)

Use these functions to evaluate the following problems: f (x) = x, g (x) = x - 3, h (x) = x^2 - 9, k (x) = 2x
