Answer:
Step-by-step explanation:
a.) the maximum is just the vertex
-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum
which in height is
-4.9*3.5714^2+35*3.5714 +1= 63.5 metres
b.) for this just plug in 2
-4.9*2^2+35*2+1= 51.4 metres
c.) just plug in f(0) =1 meter
d.) find the x intercepts (using the quadratic formula)
[tex]\frac{-35-\sqrt{35^2-4*-4.9*1}}{2*-4.9}=7.17131519096[/tex] seconds
(there is another answer but it doesn't make sense in the context of this question)
