please b Give a rule of the form f(x) = a* to define the exponential function whose graph contains the given point. (a) (3,27) (b) (-2,81) (a) The graph of the exponential function f(x) = 3x passes through the point (3,27). (Simplify your answer. Use integers or fractions for any numbers in the expression.) (b) The graph of the exponential function f(x)= passes through the point (-2,81). (Simplify your answer. Use integers or fractions for any numbers in the expression.)
(1 point) Is the function below exponential? K(x) = 7* 13.67 5 If so, write the function in the form K(x) = abr and enter the values you find for a and b in the indicated blanks below. If the function is not exponential, enter NONE in both blanks below. a = b = 02
