y-intercept for y= -3(x+2)^2 -4
----
Let x = 0,
then y = -3(2)^2-4
y = -10

Expand the (x+2)^2, then distribute the -3
(x+2)(x+2)
x%5E2+%2B+4x+%2B+4
-3%28x%5E2+%2B+4x+%2B+4%29
...
-3x%5E2+-+12x+-+12
...
y = -3x%5E2+-+12x+-+12+-+4
...
y = -3x%5E2+-+12x+-+16
...
y intercept is -16
(0, -16)

find the y-intercept for y= -3(x+2)^2 -4
At the y-intercept, x = 0
y = -3*(2^2) - 4
y = -16
