Find the quadratic function y = ax^2 bx c whose graph passes through the given points (−1,−3), (3,25), (−2,5) Hint Substitute each point into y= ax^2Hi Elliot The inverse of a function f is a function g such that g(f(x)) = x So if you have the function f(x) = ax 2 bx c (a general quadratic function), then g(f(x)) must give you the original value xYou should already see the problem there will be two functions, not one, since a function must provide a unique value in its range for each value in its domain and a quadratic maps twoThe "formula" for a parabola (in the conic sections form) is mathx^2=4cy/math (although some textbooks use mathp/math instead of mathc/math, so mathx^2=4py/math) If you put your equation into that form you can make some observatio

How to find a in y=ax^2+bx+c
How to find a in y=ax^2+bx+c- To find an axis of symmetry, start by checking the degree or largest exponential value of the polynomial If the degree of your polynomial is 2, you can find the axis of symmetry by plugging the numbers directly into the axis of symmetry formula Solve the formula and the answer you get is the xintercept of the axis of symmetryThe process of completing the square makes use of the algebraic identity = (), which represents from both sides;
