You are planning to work in the summer (13 weeks). You are deciding between working as a lifeguard or a camp counselor. The lifeguard job pays $12 per hour and a $500 signing bonus. The camp counselor job pays $15 per hour with no signing bonus. i. Write two equations that represent the salaries for these jobs.
ii. If you plan to work 5 hours a day, 5 days a week, calculate the total salaries
for each job for the summer.
iii. Which job would make you more money for the summer?

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.
