Comprehensive Applications Combining Multiple Function Types
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
Revenue is R(x)=40x, cost is C(x)=15x+200. Find the profit function P(x)=R(x)−C(x).
And one from the hard end
"Cost is C(x)=1000+20x (linear); revenue is R(x)=x(100−0.6x) (quadratic, decreasing price with volume). Find the profit function, its type, the production level maximizing profit, and the maximum profit - then state whether that level is achievable if the factory's capacity caps output at 60 units."
