Which graph is given by the radical equation y=4

answer:

The graph of a radical function. ... A radical function contains a radical expression with the independent variable (usually x) in the radicand. Usually radical equations where the radical is a square root is called square root functions.

Step-by-step explanation:

solate the radical expression involving the variable. ...

Raise both sides of the equation to the index of the radical.

If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.
