What are the solutions to the quadratic equation x2 – 16 = 0? x = 2 and x = –2 x = 4 and x = –4 x = 8 and x = –8 x = 16 and x = –16

Solve the inequality, then identify the graph of the solution. 2x – 1 > x + 2

X2 + y 2 = 36 x + y = 6 solve the system of equations.

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
