Find the range of the function y=1/2x+3 when the domain is (-2, 0, 2, 4)

The range of values for the function is (2,4,3.3,3.1)

Step-by-step explanation:

Given the expression y=1/2x+3 in the domain (-2, 0, 2, 4)

Step one : for x= - 2 we have

y=1/(2*-2)+3

y=1/-4+3

y=1/-1+3

y=-1+3

y=2

Step two :

If x is 0 we have

y=1/2*0+3

y=1/0+3

y=1+3

y=4

step three :

if x is 2

y=1/2*2+3

y=1/4+3

y=13/4

y=3.25

y =3.3

Step four :

if x is 4

y=1/2*4+3

y=1/8+3

y=25/8

y=3.1
