Find the vertex, zero(s), and y-intercept of the graph of y = 2x2 + 8x – 90. a. vertex: (–2,–98); zeros: (–5,0), (9,0) y-intercept: (0,–90) b. vertex: (2,–98); zeros: (–5,0), (9,0) y-intercept: (0,90) c. vertex: (2,98); zeros: (5,0), (–9,0) y-intercept: (0,–90) d. vertex: (–2,–98); zeros: (5,0), (–9,0) y-intercept: (0,–90)

vertex is (-2,-98)

zeros are (5,0) (-9,0)

y-intercept is (0,-90)

Step-by-step explanation:

we are given

Vertex:

we can use vertex formula

we can compare and find a,b and c

a=2 , b=8 and c=-90

so, we can plug it in formula

now, we can find y-value

so, vertex is (-2,-98)

zeros:

we can set y=0

and then we can solve for x

we can factor it

zeros are

(5,0) (-9,0)

y-intercept:

we can plug x=0 and find y

So, y-intercept is (0,-90)
