The diagram below shows the quadratic function f(x)(2,3)X O-1Find the values of h, k and a. Hence, make generalisation on the effect of change in each of the following values towards the shape and position of the graph.(a) The value of a changes to -5.(b) The value of h ...
Given a quadratic equation, most algebra students could easily form a table of ordered pairs that describe the points on the parabola. However, some may not realize you can also perform the reverse operation to derive the equation from the points. This operation is more complex, but is vital ...

How to find roots of a quadratic function?Quadratic Equations: RootsHaving a quadratic equation to solve, several steps must be followed in order to find its roots (x-intercepts): Rearrange our equation in a form ax2+bx+c=0 Factor it out if possible into a form a(x−x1)(x−x2...
The graph fails the horizontal line test as the horizontal line (in this case we can use the x-axis as our horizontal line) intersects with the graph at multiple points. Therefore, the function does not have an inverse. How to Find the Inverse of a Quadratic Function & ...
