It seems that this question would make more sense if it were: Which ordered pair can be a solution of h(t)=-16^2+80t

All alternatives but B) cannot be a solution for the function.

Step-by-step explanation:

Here we have t=x

So, we may write the funtion as: h(x)=-16^2+80x

h(x)=y

Let's test all the points:

A) (1, 64)

$h(1)=-16^2+80(1)\\h(1)=-256+80\\h(1)=-176$

B) (2, 96)

$h(2)=-16^2+80(2)\\h(2)=-256+160\\h(2)=96$

C) (-4, 256)

$h(-4)=-16^2+80(-4)\\h(-4)=-256-320\\h(-4)=-576$

D) (5, 0)

$h(5)=-16^2+80(5)\\h(5)=144$
