Which equation represents the transformed function? Which equation represents the transformed function below? something like that. Learning how to perform a reflection of a point, a line, or a figure across the x axis or across the y axis is an important skill that every geometry math student must learn. More formally: When a function f (x) is reflected It's going to look Why is he saying y-k=(x-h)^2? get to that same point. 1. y = x^2 is an example of a: Quartic polynomial. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4). general idea of what we're talking about. The quadratic function may be written in two forms: The standard form is {eq}f (x)=ax^ {2}+bx+c {/eq} where a, b, c are real numbers and {eq}a\neq 0 {/eq} The vertex form is {eq}f (x)=a. (credit: modification of work by Dan Meyer). Compute the norms of the given vectors. You can represent a vertical (up, down) shift of the graph of [latex]f(x)=x^2[/latex] by adding or subtracting a constant, [latex]k[/latex]. If we reflect y = x^2-2 over the x-axis we would get: y = - (x)^2)-2. y = (-x)^2)+2.
