Graph the parabola and give its vertex, axis, x-intercepts, and y-intercepts.f(x) = x2 + 10x
A. vertex (5, -25); axis is x = 5;
x-intercepts are 0 and 10; y-intercept is 0
B. vertex (-5, -25); axis is x = -5;
x-intercepts are 0 and - 10; y-intercept is 0
C. vertex (5, 25); axis is x = 5;
no x-intercepts; y intercept is 50
D. vertex (-5, 25); axis is x = -5;
no x-intercepts; y-intercept is 50
