D.)

Consider the quadratic function f(x) = x2 - 5x + 6. What are the values of the coefficients and constant in the function? a = b = c =

Which table represents a quadratic function?

C.)

Which graph has a rate of change equal to 1/3 in the interval between 0 and 3 on the x-axis?

C.)

Which function increases at a faster rate on 0 to infinity, f(x) = x2 or g(x) = 2x? Explain your reasoning.

Using a table of values, the outputs of f(x) for whole numbers are 0, 1, 4, 9, 16, 25, 36, and so on. For the same input values, g(x) has outputs of 1, 2, 4, 8, 16, 32, and 64. Continuing to double the output each time results in larger outputs than those of f(x). The exponential function, g(x), has a constant multiplicative rate of change and will increase at a faster rate than the quadratic function
