Match the functions to the ranges when the domain is (1,2) ... f (x) = 3x + 5 F (x) = x^2 - 2x - 5 F (x) = (x+5) x^2 F (x) = 4-x

Dommain is input

range is output from given input (domain)

1,2

just input 1 for x and evaluate

then input 2 for x and evaluate

f (x) = 3x

f (1) = 3 (1) = 3

f (2) = 3 (2) = 6

range = (3,6)

f (x) = x^2-2x-5

f (1) = 1^2-2 (1) - 5=1-2-5=-6

f (2) = 2^2-2 (2) - 5=-5

range = (-6,-5)

f (x) = (x+5) x^2

f (1) = (1+5) (1^2) = (6) (1) = 6

f (2) = (2+5) (2^2) = (7) (4) = 28

range = (6,28)

f (x) = 4-x

f (1) = 4-1=3

f (2) = 4-2=2

range = (3,2)
