Find the quadratic function y=f(x) that has a vertex of (2, 3) and passes through the point (0, -5). a) Write the function in standard form f(x)= a(x-h)+k: b) Write the function in general form f(x) = ax +bx+c: 3) The total cost of a product is C= 2200 - 45x+x where x represents the number of items produced and C is measured in dollars. a) How many items should be produced to minimize the total cost? b) What is the minimum cost? 4) The height h (in feet) of a baseball hit into the air can be modeled by the function h(t)= -16t + 56t+3, where t is the time measured in seconds. a) How long does it take the baseball to reach its maximum height? b) What is the maximum height of the baseball?
