Jon punts the football from ground level, its distance above the ground is given by d(t)=70t-16t^2, d(t) is in feet and t is in seconds
a. use definition of derivative as difference quotient of function d.
I already did that and got 70-32a or 70-32t (I used (f(a+h)-f(a))/h))
b. Find the equation of the line tangent to the graph of f at the point where t=3
I'm sure if I got this right but I got y=-26x+144
by doing y-66=-26(x-3)
c. Neglecting air resistance, how long will the ball be in the air? (known as hang time)
This, I have no idea.
