The set of output values are (1,3,11,17) as Range

Step-by-step explanation:

Given function is f (x) = 2x-3 and domain is (-1,0,4,7)

Function is given that taking set of input values from domain and give out set of output values.

For x = (-1)

f (x) = 2x-3

f (-1) = 2 (-1) + 3 = (-2) + 3=1

For x=0

f (x) = 2x-3

f (0) = 2 (0) + 3=3

For x=4

f (x) = 2x-3

f (4) = 2 (4) + 3=-8+3=11

For x=7

f (x) = 2x-3

f (7) = 2 (7) + 3=14+3=17

Thus,

The set of output values are (1,3,11,17) as Range
