To find the y-intercept, plug in x = 0 and solve for y

The y-intercept is the point (0,8)

-------------------------------------------------------

To find the x-intercept, plug in y = 0 and solve for x

BUT, there's a problem. Plugging in x = 64 into gives you

which is NOT y = 0, so clearly x = 64 is an extraneous solution.

So there are NO x-intercepts. This means that the graph does NOT cross the x-axis at all.
