Question

What is the `y`-intercept of `y=3(x-8)^2 + 15`?

Answer 1

The y-intercept is (0,207)

Explanation:

The y-intercept occurs when x=0, so all we need to do is substitute x=0 into the function.

`y=3(0-8)^2+15`
`y=3(64)+15`
`y=192+15`
`y=207`

Hence, the y-intercept is (0,207)

Hope that helps :)
