Gretel · Answer 1

Domain is inputs, input the domain for x

y=5 (-1.2) - 2

y=-6-2

y=-8

y=5 (0) - 2

y=0-2

y=-2

y=5 (4) - 2

y=20-2

y=18

range is {-8, - 2, 18}

Sasha Richmond · Answer 2

For x = 0,

we substitute zero into the equation to find its y value like so:

y = 5x-2

y = 5 (0) - 2

y = - 2

There you go.
