Question

​Given the following​ functions, find the indicated values.

f(x)=1-2x


a. f(-2)

b.​ f(0)

c.​ f(​2)

Answer 1

Answer: 5, 1, -3

Explanation:

1. f(-2) = 1-2x(-2) = 1+4 =5 ; f(-2)= 5

2. f(0) = 1-2(0) = 1-0 = 1 ; f(0) = 1

3. f(2) = 1-2(2) = 1-4 = -3 ; f(2) = -3

Answer 2

Answer: {5, 1, 3}

Explanation:
Plug in the numbers in parentheses for x.

a: f(-2) = 1-2(-2) = 1+4 = 5

b: f(0) = 1-2(0) = 1-0 = 1

c: f(2) = 1-2(2) = 1-4 = -3
