When is a geometric series converging? diverging? - Correct Answer -
Converging: abs. value 'r' < 0
Diverging: abs. value 'r' > 0
What is another word for equation of a series? - Correct Answer -
general term
Equation for compound interest - Correct Answer - A=P(1+r/n)^nt
How do you find a single term in a binomial expansion - Correct Answer
- (nCr)(a)^n-r (b)^r
r = the term number minus 1
How do you draw a sign diagram? - Correct Answer - Mark all x-
intercepts, and mark in each section if it is in the positive or negative
section. Dotted line for asymptotes
, What are some properties of inverse/one-to-one functions? - Correct
Answer - domain of f(x)=range of f⁻¹(x) and vice versa
Means that for every y value there is only one x value and for every x
value there is only one y value
(has to be able to pass the vertical line test both ways)
How do you find an inverse function? - Correct Answer - switch x and y
and solve for y
What are reciprocal/self inverse functions? - Correct Answer - f(x)=f⁻¹(x)
symmetrical over the line y=x
HOY VUX - Correct Answer - Horizontal, zero slope, y=#
Vertical, undefined slope, x=#
How do you find the shortest distance from a point to a line Ax+by+C=0?
- Correct Answer - Abs. value (Ax1+By1+c)/[root(A²+B²)]
Stretch of a graph - Correct Answer - a 2x stretch would make it so that
each point is twice as far from the 0 line as before
When the number is less than 1, it is called a compression
