| Question | Answer | % Correct |
|---|---|---|
| lim x->9 (8x) Continuous or discontinuous? | Continuous | 91%
|
| Which of the following functions have two infinite x and y discontinuities, each the same value? | 1/x | 65%
|
| What is a tangent line of a function? | The line that touches exactly one point on a function | 62%
|
| What is a secant line of a function? | Any line between two points on a function | 58%
|
| Which of the following is a method of algebraically finding the a- and a+ limits of a function with a jump discontinuity, given that x=a? | Use a table, creating a list of x-values from each side of a that get closer and closer to a, and by plugging them into the function, you can get an answer that approximates the limits of both sides. | 56%
|
| What is the limit of (5x^3-7)/(2x^3+5) as x approaches infinity? | 5/2 | 55%
|
| How can you best algebraically evaluate limits that have radicals in them? | Use the conjugate method by multiplying the numerator and denominator by a certain number that simplifies the fraction to something you can evaluate without getting an undefined. | 48%
|
| How do we algebraically evaluate the limits of functions approaching infinity? | Rule out all unneeded constants and smaller terms and evaluate the term(s) with the degree of the equation. | 43%
|
| If a piecewise function has f(x) values defined for only x<6 and x>6 then is it continuous? | Jump Discontinuity | 40%
|
| What is a cosecant line of a function? | Doesn't exist | 34%
