a function is initially defined by the set of coordinate pairs {(-3,7), (1,5),(4,13)}. Which coordinate pair below, if added to this set, prevents the set from representing a function?

Factor the polynomial by its greatest common monomial factor.

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.

Evaluate each expression. determine if the final simplified form of the expression is positive or negative -42 (-4)2 42
