In a physics lab, an artifact is dropped from the roof of the school building, 98 feet above the ground. The height ݄ (in feet) of the ball above the ground is given by the function h(t)=-16t^2+98, where t is the time in seconds.

The algebraic expression h = 16 feet.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
