When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What is the equation of the line tangent to #f(x)=1/abs(x) # at #x=1#?
- How do you find the average rate of change for the function #f(x)= x^3 -2x# on the indicated intervals [0, 4]?
- How do you find the points where the graph of the function #y=(4x)/(x+1)# has horizontal tangents and what is the equation?
- How do you use the limit definition of the derivative to find the derivative of #f(x)=sqrtx#?
- How do you find the coordinates of the two points on the #x^2-2x+4y^2+16y+1=0# closed curve where the line tangent to the curve is vertical?
