When x = 3, what is the y value for -2(3)^2 + 32? See the table above.
That’s it — 2 points!

Rate of change = slope.
The equation of a line is y = mx + b where m is slope
Look at the equation above — what is m?
Is it positive or negative?
Increasing or decreasing?

Put this equation into the TI-84. It is a nonlinear graph leaving out answer (2).
It is not a quadratic or x^2 which narrows it further!!

not dependent on the height:
(3) and (4) each have an “h” and an “h” appears twice in the long formula for A: A = 2lw + 2 hw + 2lh. Look for the one with no “h” at all.

Look carefully at the graphs for the only one that decreases for x = 10 thru 40! 2 points :)
Finding the right graph is apparent but why his profit follows this pattern we will never know!
