Need some help on this please! Will give brainlist!! :))

Standard Form

This is a freefall question in feet so a = -16

Since it starts at 50 feet c = 50

So we have the equation f(x) = -16x^2 + bx + 50

plug in 1.5 for x and 88 for y to find b

88 = -16(1.5)^2 + 1.5b + 50

88 = 14 + 1.5b

74 = 1.5b

b =  148/3

f(x) =

Vertex Form

the vertex is (h,k) or (1.5,88) since it is the highest point

f(x) =

Graph

(see first picture at bottom)

Vertex

Vertex is (1.5, 88) since the maximum height is 88 at 1.5 seconds

Y-Intercept

y-intercept is 50 because it starts at 50 feet

Zeros

use quadratic formula (see second picture at bottom)

zeros =

= 3.8872 and -0.8039

zeroes represent when the ball hits the ground

answer is : muchas/tipicas

have a nice day!
