math 2: parametric equations & piecewise funcitons Flashcards
1
Q
(ch 10) parametric equation:
A
x= x(t), y = y(t)
2
Q
piecewise functions are defined by different equations on
A
different parts of their domain
3
Q
absolute value functions: |x| =
A
{x if x ≥ 0
{-x if x
4
Q
general absolute value function has the form
A
f(x) = a|x-h| + k
5
Q
h delineates the domain of all real numbers into
A
2 parts
6
Q
the values are the slopes of the sides
A
a
7
Q
step functions are constant over different parts of their domain, so that their graphs consist of
A
horizontal segments
8
Q
greatest integer function is an example of
A
the step function
9
Q
if x is an integer →
A
[x] = x
10
Q
if x isn’t an integer [x] is the
A
largest integer less than x
