To find the x - coordinate of the vertex we use formula <span>x=−<span>b<span>/2<span>a=8/4=2
or x=2, f(2)=-2
so the vertex is V(2, -2)
so the answer is </span></span></span></span>
<span>Minimum at (2, –2)
</span>
You can baby sit, walk dogs or dogsit!
you can mow lawns and take care of gardens!
If the diver has not jumped yet (t = 0) then his feet must be on the diving board. therefore plug in 0 and solve.
h(t) = -4.9(0) + 91 + 3 = 94 meters
but this seems extremely high so please check that you have copied the question down correctly.
