The graph below shows the height of a projectile t seconds after it is launched. If acceleration due to gravity is –16 ft/s2, which equation models the height of the projectile correctly? h(t) = at2 + vt + h0

h(t) = –16t2 + 42t + 5
h(t) = –16t2 + 5
h(t) = –16t2 + 32
h(t) = –16t2 + 32t + 5

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
