Question 1

Tutorial Exercise Find two positive real numbers whose product is a maximum. The sum of the first and three times the second is 60. Step 1 Let x be the first number and y be the second number. Write an equation describing the sum in this problem. X + yWrite the standard form of the quadratic function whose graph is a parabola with the given vertex and that passes through the given point. (Let x be the independent variable and y be the dependent variable.) Vertex: (6, 1); point: (0, 8) Ex Write the standard form of the quadratic function whose graph is a parabola with the given vertex and that passes through the given point. (Let x be the independent variable and y be the dependent variable.) Vertex: (2, 1D); point: (D, 2) Ex
