Question

Using the domain values {-1, 0, 4}, how do you find the range values for relation y=2x-10?

Answer 1

`y in{-12,-10,-2}`

Explanation:

`"substitute the values from the domain into "y=2x-10`

`x=color(red)(-1)toy=2(color(red)(-1))-10=-12`

`x=color(red)(0)toy=2(color(red)(0))-10=-10`

`x=color(red)(4)toy=2(color(red)(4))-10=-2`

`"range is "y in{-12,-10,-2}`
