What Is The Range If The Domain Are 2,1,-1,-2, In A F(X) = 2x +1?

What is the range if the domain are 2,1,-1,-2, in a f(x) = 2x +1?

 

Answer:

Range: 5, 3, -1, -3

Step-by-step explanation:

Domain : 2, 1, -1, -2

A. f(x) = 2x + 1, when x = 2

y = 2x +1

y = 2(2) + 1

y = 4 + 1

y = 5

B. f(x) = 2x + 1, when x = 1

y = 2x +1

y = 2(1) + 1

y = 2 + 1

y = 3

C. f(x) = 2x + 1, when x = -1

y = 2x +1

y = 2(-1) + 1

y = -2 + 1

y = -1

D. f(x) = 2x + 1, when x = -2

y = 2x +1

y = 2(-2) + 1

y = -4 + 1

y = -3
