Graph the parabola and give its vertex, axis, x-intercepts, and y-intercepts.f(x) = -x2 - 8x
A. vertex (4, -16); axis is x = 4;
no x-intercepts; y-intercept is -32
B. vertex (4, 16); axis is x = 4;
x-intercepts are 0 and 8; y-intercept is 0
C. vertex (-4, 16); axis is x = -4;
x-intercepts are 0 and -8; y-intercept is 0
D. vertex (-4, -16); axis is x = -4;
no x-intercepts; y-intercept is -32
