1. Given a polynomial P(x) = x³-4x²-5x. 5 is one of the zeroes. a) Factorise P(x) completely
b) Sketch the graph of P(x)
C)Find the domain and range

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
