Question

graph the function. specity the vertex, axis of symmetry, max and min value and intercepts
s=-1/4t^2+t-1

Answer 1

i take it this is
\[s(t)=-\frac{1}{4}t^2+t-1\]

Answer 2

for vertex ( and axis of symmetry) use
\[t=-\frac{b}{2a}\] with
\[a=-\frac{1}{4},b=1\]

Answer 3

or if you really want to be clever write it as
\[s(t)=-\frac{1}{4}(t-2)^2\]and observe that it is a parabola that opens down the vertex at (2,0)

Answer 4

so is the vertex anfd the axis the same thing?
