The quadratic function is a second order polynomial function: f(x) = ax 2 + bx + c. How are these graphs related? This problem is all about the exponential function and the basic information we need to know, starting with its equation. Graph the given functions on a common screen.So how do we find the equation of curve from the graph (curve on the graph is similar to the graph of the quadratic function)? Engineering Mathematics.Since we will be graphing these functions on the x, y coordinate axes, we can express the parabolas this way: y = 1.5x 2 - 9x + 11.5 Of course, quadratic functions, or second degree polynomial functions, graph as parabolas. Our example will use these two quadratic functions: f(x) = 1.5x 2 - 9x + 11.5.Here, we can observe that vertical asymptote shifted from x = 0 to x = 3. What is an equation for the function? Since, the graph of the parent function moves down, Therefore Option Option B and D are incorrect.
