Moderate# Piecewise Quadratic Function

APCALC-SS6KEU

Given the piecewise function:

$$f(x) = \left\{ {\begin{array}{*{20}{c}} {2{x^2} - 3x + 7}&{x \le 3}\\\ {{x^2} - 9}&{x > 3} \end{array}} \right.$$

Find any value(s) of $x$ where $f(x)$ is discontinuous and describe what kind of discontinuity it is.
