Limits and Continuity
Which technique is most appropriate for evaluating when ?
Using L'Hôpital's Rule immediately without any preliminary algebraic manipulation.
Direct substitution of into the expression.
Expanding using binomial expansion and then taking a limit.
Multiplying by the conjugate of the numerator to rationalize it before taking the limit.
If the function has a vertical asymptote at , how does changing the parameter to affect the location of the vertical asymptote?
The vertical asymptote becomes horizontal.
The function no longer has a vertical asymptote for any value of .
It does not change; the vertical asymptote remains at .
The vertical asymptote moves left if and right if .
Determine the limit as x approaches 2 of the function .
9/2.
The limit does not exist.
The limit is infinite.
15/4.
If a function has a discontinuity at and is defined elsewhere, how might one find ?
Evaluate limits from both sides of to check if they are equal.
Integrate from to and divide by two.
Multiply by and evaluate at .
Set equal to zero since there's a discontinuity at .

What’s an asymptote?
A line that touches a point on a curve.
A point where a graph intersects the x-axis.
A point where a graph intersects the y-axis.
A line that a graph approaches but doesn’t touch.
