Quinton Stephens · Answer 1

(f+g) (x) = 2x-3

(k+g) (x) = 3x-3

(f-k) (x) = - x

(k-g) (x) = x+3

Step-by-step explanation:

(f+g) (x)

x + x - 3

2x - 3

(k+g) (x)

2x + x - 3

3x - 3

(f-k) (x)

x - (2x)

-x

(k-g) (x)

2x - (x - 3)

2x - 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(f+g) (x)(k+g) (x)(f-k) (x)(k-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

(f+g) (x)

(k+g) (x)

(f-k) (x)

(k-g) (x)
