For finding range of the function “g” we use given domain “D” values

Here we have

g(x) = 2x-5……(1)

We substitute domain values into equation (1) one by one and get the range values

( Here domain values are the value of “x” )

putting value X=-2 in equation (1)

g(-2) = 2(-2)-5

g(-2)= -4-5=-9

putting value of X=0 in equation (1)

g(0) = 2(0)-5

g(0)= 0-5=-5

putting value of X=2 in equation (1)

g(2) = 2(2)-5

g(2)= 4-5=-1

putting value of X=4 in equation (1)

g(4) = 2(4)-5

g(4)= 8-5=3

The range of function “g” is

{-9,-5,-1,3} ans .
