Evaluate the function.

a. f (x) = 3x+5 {-2,0,2}

b. g (x) = x-9 find g (5)

c. f (n) = (3-n) + 4 {-1,-2,3}

Part a) The values of the function f (x) are {-1,5,11}

Part b) The value of g (5) is - 4

Part c) The values of the function f (n) are {8,9,4}

Step-by-step explanation:

Part a) we have

f (x) = 3x+5

Evaluate for {-2,0,2}

1) For x=-2

substitute the value of x in the function

f (-2) = 3 (-2) + 5=-1

2) For x=0

substitute the value of x in the function

f (0) = 3 (0) + 5=5

3) For x=2

substitute the value of x in the function

f (2) = 3 (2) + 5=11

Part b) we have

g (x) = x-9

Evaluate for x=5

substitute the value of x in the function

g (5) = 5-9=-4

Part c) we have

f (n) = (3-n) + 4

Evaluate for {-1,-2,3}

1) For n=-1

substitute the value of n in the function

f (-1) = (3 - (-1)) + 4=8

2) For n=-2

substitute the value of n in the function

f (-2) = (3 - (-2)) + 4=9

3) For n=3

substitute the value of n in the function

f (3) = (3 - (3)) + 4=4
