Leila is choosing between two exercise routines.

In Routine #1, she burns 47 calories walking. She then runs at a rate that burns 7.75 calories per minute.
In Routine #2, she burns 25 calories walking. She then runs at a rate that burns 10.5 calories per minute.
For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?
Use t for the number of minutes spent running, and solve your inequality for t.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
