Find the range of the given domain.

Question

f(x)=2x+8;{-2,-2,0,1,2}
What is the range?
A. {4,7,8,11,12}
B. {4,6,8,10,12}
C. {4,7,7,11,12}
D. {3,6,8,10,13}

Answer 1

To find the range of this function, we need to substitute each value from the domain into the function and see what output we get.

For f(-2):
f(-2) = 2(-2) + 8 = 4

For f(-1):
f(-1) = 2(-1) + 8 = 6

For f(0):
f(0) = 2(0) + 8 = 8

For f(1):
f(1) = 2(1) + 8 = 10

For f(2):
f(2) = 2(2) + 8 = 12

The range is the set of all the outputs we obtained from the function.

Therefore, the range of the function f(x) = 2x + 8;{-2,-1,0,1,2} is {4,6,8,10,12}.

The correct option is B. {4,6,8,10,12}
