I'm so confused by these equations can you please explain it to me?

Question 1: 20 pts Determine whether f is an exponential function of x. If so, find the constant ratio. -1 0 1 2 f (x) 3 12 48 Of is an exponential function with a constant ratio of 4. Of is an exponential function with a constant ratio of 1/4. Of is an exponential with a constant difference of 4. Of is not an exponential function. Question 2: 20 pts- Determine whether f is an exponential function of. x. If so. find the constant ratio. X 10 1 2 3 1(x) Of is an exponential function with a constant ratio of 1/2.
