Select the graph that represents $f\left(x\right)=\frac{x^2-16}{x-4}$f(x)=x2−16x−4.
If $P$P($x$x)=$\frac{1}{x^2-1}$1x2−1, find:
If $f\left(t\right)=\frac{t^3+27}{t^2+9}$f(t)=t3+27t2+9 evaluate the following.
For which two values of $x$x is $f\left(x\right)=\frac{3x+5}{x^2+4x}$f(x)=3x+5x2+4x discontinuous?
