1. The dose-response for a specific drug is f(x)=(100x^2)/(x^2+0.15), where f(x)fx is the percent of relief obtained from a dose of x grams of a drug, where 0 ≤ x ≤1.5
Find f'(0.4) and select the appropriate units.
2. f(x)=(7x^2+4x+3)/(√x) then f(x)=? and f(3)=?
3. If f(x)=(7x + 7)/(2x+2), then f(x) =? and f(5)=?
