The question is asking you to input the numbers into the equation to get an output. Since they want you to replace x with a number, let’s put 3 in place of x in both equations. In this example, 5^3 = 125 and 25*3 = 75. This is one number that shows f(x) as a higher interval than g(x). That means you want 3 in your answer, so B and D are wrong since they do not include 3 as a solution. Next, you need to figure out what set of solutions are correct. If you replace x with 2, 5^2 = 25 is less than 25*2 = 50, therefore, A cannot be your answer either as 2 is not part of our set of solutions. Since C is all we’re let with, let’s double check to make sure it’s right. If we input 6 into both equations, we get 5^6 = 15625 being much greater than 25*6 = 150. Since 3 and 6 are now a part of our set of solutions, the only answer that has both of them is C, so our answer must be C.
