Interpret the following exponential function: y is equal to 9 times 0 point 7 7 to the x th power What is the growth/decay factor? What is the y -intercept?

In y = 9(0.77)^x, the base 0.77 is between 0 and 1, so it is the decay factor. The y-intercept is the value of y when x = 0: y = 9(0.77)^0 = 9, so the correct choice is “Decay factor is 0.77; y-intercept is 9.”
