To know which point belongs to the given function, substitute with the x value in the function and calculate the corresponding y as follows: At x = -1: y = f(-1) = 4 * (5)^(2*-1) = 4/25 (choice A is correct) At x = 0: y = f(0) = 4* (5)(2*0) = 4 (choice B is wrong) At x = 1: y = f(1) = 4* (5)(2*1) = 100 (choice C is wrong) At x = 2: y = f(2) = 4* (5)(2*2) = 2500 (choice D is correct)
Based on the above calculations: Choices A and D are both correct
