The function y=−16x2+v0x models lindy's height in feet above a trampoline x seconds after she jumps straight up. in the equation of the function, v0 is her initial velocity in feet per second. lindy lands back on the trampoline 1 second after she jumps.

The initial velocity of Lindy was 16 ft/s

Step-by-step explanation:

Given:

It is function models of Lindy's Height in feet above a trampoline x seconds after she jumps straight up.

In the equation of the function

is initial velocity in feet per second.

We need to find the initial speed of Lindy

If She lands back on the trampoline after 1 seconds.

It means y must be zero because she lands back on trampoline.

At x=1, y must be 0

Hence, The initial velocity of Lindy was 16 ft/s

range is infinite on both x and y axis positive and negative
