Aball is thrown vertically upward from the top of a 100-foot tower, with an initial velocity of 20 ft/sec. its position function is s(t) = –16t2 + 20t + 100. what is its velocity in ft/sec when t = 1 second? (this is calculus, involving limits, and explain, because i mostly just need to know how to do this. : ) )

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
