Question

What is the range of the function f(x) = 2x + 1 given the Domain D = {-1,0, 1, 2}?

R = {0, 1,3,5)

R= {-1,1,3,5)

R = {-5, -3,-1,1)

R = {0, 1,3,6}

Answer 1

R= {-1,1,3,5)

Explanation:

To find the range, use the domain values as the input and find the output for the function

Domain D = {-1,0, 1, 2}?

f(x) = 2x + 1

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

f(0) = 0 + 1=1

f(1) = 2 + 1 = 3

f(2) = 4 + 1 = 5

The range is { -1,1,3,5}
