Match the functions to their ranges when the domain is {1, 2}.
f(x) = 4 - X
f(x) = 3x + 5
f(x) = x2 – 2x-5
f(x) = (x + 5)2
{-6, -5}
{8, 11}
{3,2}
{6, 28)

1) {3,2}

2) {8,11}

3) {-6,-5}

4) I see no match! (x+5)*2 has a range of {12,14}

Step-by-step explanation:

you substitute x with the first number of the domain (1) and you get the related range limit

then you should do the same with the other limit of the domain (2) and you get the other limit

answer: 12

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
