This is 11th grade Advanced Algebra C&C. Please show complete show work with step by step explanation so I will understand. I really need help asap.

25. Suppose a sheet of paper is repeatedly folded in half. The function A(n) = A. (2) models the area of the sheet of paper after n folds. What is the A-intercept of the graph of A (n)? AO cn 1 B 2 DA 26. Graph the piecewise-defined function f(x) given below. Then describe the function's domain and range and any intercepts that the graph has. -2x - 2 if x 5 2 6 827. The graph of which function is shown? Ay= VX+2 By= \\x-2 Cy= Vx+2 Dy= VX-2 28. Consider the function f(x) = 2x2 + 4x - 30. Classify each statement. a. The vertex of the graph of f(x) is (1, -32). O True OFalse b. The zeros of f(x) are x = 3 and x - -5. O True OFalse c. The graph of f(x) opens down. O True O False d. The axis of symmetry is x = -1. O True O False e. The y-intercept of f(x) is -30. a True O False 29. The population of city A was 12,831 in 1900 and grew 5% per year for the next 10 years. For the same period, the function P(1) = 11, 572(1.07)t models the population of city B, where P is the population and t is the time. in years since 1900. a. What was the population of each city in 1900? Which city had the greater population? b. At what annual rate was the population of each city increasing over this period? The population of which city was growing faster? c. What was the population of each city in 1910? Which city had the greater population
