Give the rule that describes the piecewise-defined function in the graph below. Write the rule for the function. Select the correct choice below and fill in the answer boxes to complete your choice. (Type an exact answer, using radicals as needed. Do not factor. Type integers or simplified fractions.) A. \( f(x)=\left\{\begin{array}{lr}\text { if } & \leq x< \\ \text { if } & x \geq\end{array}\right. \) B. \( f(x)=\left\{\begin{array}{ll}\text { if } x \leq \\ \text { if } x>\end{array}\right. \) ... \( \int \quad \) if \( x \geq \) \( f(x)=\left\{\begin{array}{ll}\text { if } x \leq \\ \text { if } x>\end{array}\right. \) \( f(x)=\left\{\begin{array}{ll}\text { if } x \geq\end{array}\right. \)
