Answer 1

-8.

Explanation:

You can get the y-intercept when you find the y-value when x = 0.

y = x^2 - 8

y = 0^2 - 8

y = 0 - 8

y = -8

So, the y-intercept is -8.

Hope this helps!

Answer 2

y = -8, if x2 mean 2 times x.

y = -7, if x2 mean X^2

Explanation:

Y-intercept mean x = 0.

Plug x = 0, into the parabola, you get the answer.
