Practice problem
Which of the following functions is a jump discontinuity?
{lnxx≤41000−42x400xx>4\begin{cases}\ln x&x\leq4\\\frac{1000-42x}{400x}&x>4\end{cases}{lnx400x1000−42xx≤4x>4
{ln(x)+1x≤45000−57x500xx>4\begin{cases}\ln(x) +1&x\leq4\\\frac{5000-57x}{500x}&x>4\end{cases}{ln(x)+1500x5000−57xx≤4x>4
Type a concept, like “slope” or “photosynthesis”.
