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

Question 5: 10 pts - Simplify In e -12 -121 12 O -12 121 Question 6: 10 pts Determine whether f is an exponential function of x. If so, find the constant ratio. -1 0 1 2 1 ( x ) 1 5 1 2 Of is an exponential function with a constant ratio of 2. Of is an exponential function with a constant ratio of 1/2. Of is an exponential with a constant difference of 2. Of is not an exponential function. Question 7: 10 pts What change do you have to make to the graph of f(x) = 5% in order to graph the function g(x) = 57 - 3? Shift the graph units 5, down 3, down 3, up 5, up None of these Question 8: 10 pts
