y = -8

Explanation:

Set x = 0 in the function g(x). By definition, the y-intercept is the value at which x = 0. Plugging this in, we're left with g(0) = -8. In general, the coordinate for the y-intercept is:

(0, y).

Similarly, the coordinate for the x intercept is

(x, 0).

To find the x-intercept, you must set g(x) = 0 and solve for x.
