Explain how you could use the formula

(x + a)2 = x2 + 2ax + a2

to solve the quadratic equation

x2 + 5x - 24 = 0.

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
