Question

Hi there!

Thanks for stopping by. Can you help me with this Applied Calculus homework? #2 and #4, I can do the rest.

Thansk!

Answer 1

2. The plot represents a function that is continuous at
`x=a` - that is, there are no breakages in plotted curve - so

`\displaystyle\lim_(x\to a)f(x)=f(a)=b`

4. Unlike in (2), there is a jump discontinuity which makes the limit as
`x\to a` non-existent.
