Target F To Graph the Cube Root Function
We will be graphing the square root function.

math f(x)={\sqrt[3]{x}} math

When we graph this function we need to consider what domain we have based on the cube root function. Unlike the square root function in Target 6E, we have no restrictions on the domain. We can take the cube root of any real number, positive or negative. So our domain will be all real numbers.

When choosing our domain to make the numbers easier to graph we will choose numbers that are perfect cubes. Know that this is a continuous function, therefore our domain includes all real numbers, those that are perfect cubes and those which are not.
