Find the vertex, zero(s), and y-intercept of the graph of y = –x2 + 4x + 32.

xxMikexx [17]

Answer:

The correct option is A.

Step-by-step explanation:

The given equation is

$y=-x^2+4x+32$

Put x=0, in the given equation.

$y=-(0)^2+4(0)+32=32$

The y-intercept is (0,32).

Put y=0, to find the x-intercept.

$0=-x^2+4x+32$

$0=-x^2+8x-4x+32$

$0=-x(x-8)-4(x-8)$

$0=-(x+4)(x-8)$

$x=-4,8$

Therefore the y-intercepts are (-4,0) and (8,0).

The vertex of a parabola $f(x)=ax^2+bx+c$ is

$(-\frac{b}{2a},f(-\frac{b}{2a}))$

$-\frac{b}{2a}=-\frac{4}{2(-1)}=2$

Put x=2 in the given function.

$y=-(2)^2+4(2)+32$

$y=-4+8+32$

$y=36$

The vertex is (2,36).

Therefore option A is correct.
