The cost to produce a certain product depends on 3 main variables, denoted p, q, and r. if c(p, q, r) = c0e−2p + 7q − 9r represents the cost function, find the greatest rate of decrease of this function at the point p0(100, 55,

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
