Key Terms Part #1
What operation is Quotient? Name other ways to say the same thing
Division, half or a third
What are three other terms to that mean solution?
roots, zeroes, x-intercept
What is the slope of a horizontal line?
zero
What type of circle and line goes with <,>?
open circle, dotted line
How can you tell if the graph of a linear function is increasing or decreasing?
increasing is going up from left to right, decreasing is going down from left to right
What operation is DIFFERENCE? Name others ways to signify the same operatoin
Subtraction, less: less than(turn around phrase)
What is another way to write f(x)=?
y=
What is the slope of a vertical line?
undefined
What type of circle and line goes with less than or equal to?
closed circle, solid line
How can you tell if the graph of a quadratic function has a maximum or minimum?
Max is vertex on "n" shaped or negative quadratic, Min is vertex on "u" shaped or positive quadratic
What operation is SUM? Name other ways to denote the same thing
Addition, more: more than (turn around phrase)
What is the domain?
all of the x values in a relation
How do you find the slope from a graph?
use Rise/Run....rise divided by run.... change in y/change in x
If a point is on a dotted line, is it a solution to a system of inequalities?
no, solid line or shaded region
How can you tell if the graph of an exponential function is increasing or decreasing?
Increasing curve goes up from left to right, decreasing curve goes down from left to right
What operation is PRODUCT? Name other ways to say the same thing
Multiplication, times, twice, triple
What is the range?
all the y values in a relation
What is the slope of the linear equation:
y=3x - 5?
slope=3
If two lines never intersect, what can you tell about their slopes and how many solutions they have?
same slope, no solutions
What is the Domain of a linear, quadratic and exponential function?
All real numbers
What is the "turn around" word? Give an example
"than" five less than a number is written x-5
How can you tell if a relation is a function from:
Mapping? Graph? Set notation?
Mapping: one line from each left side
Graph: Pass the vertical line test
Set notation: No x value repeats
What is a y-intercept and how do you find it?
point where graph crosses the y axis, it is "b" in y=mx+b
If two lines coincide, what can you say about the slopes and number of solutions?
same slope, infinite many solutions
What is the range of a linear, quadratic and exponential functions?
linear= all real numbers
quadratic= greater than/less than or equal to K in vertex
Exponential= > or < the horizontal asymptote
