Home Square Root Function f(x) = x. The graph of the square root function is related to y = x 2. Getting the graph of a square root function using TikZ. I may help you answer it but since the solution is complex, I doubt you will really understand the whole process of solving it so it's recommended that you really have to ask someone to explain it to you in person to make the explaining clearer. 2. y = x 2 + 1. Video transcript. In the graph below we have radical functions with different values . Graphing a Basic Square Root Function. Basically, replace \color{red}f\left( x \right) by \color{red}y , interchange x and y in the equation, solve for y which soon will be replaced by the . {eq}f (x) = \sqrt {x} \text { or } y = \sqrt {x} {/eq} To construct the graph for the parent . Find the domain for y = x 2 y = x - 2 so that a list of x x values can be picked to find a list of points, which will help graphing the radical.
