What is the Domain and Range of the table?
What is Domain: {-4,-3,-1,2,3,6}, Range: {-7,-6,-1,-7,2,5}
100
In what Quadrant are the x values positive and the y values negative?
What is Quadrant IV
100
How do we know if a relation is a function?
What is every x value corresponds to only one y value.
100
What is a pictorial representation of a mathematical relationship?
What is a graph.
200
Find f(x) = 4x - 5 for f(2)
What is f(2) = 3
200
Find the inverse of the mapping.
What is {(2,8), (-3,7), (5,7), (4,-6)}
200
What are the x and y intercepts?
What is the x-intercept is the point where the line crosses the x-axis. The y-intercept is the point where the line crosses the y-axis.
200
Determin if the relation is a function.
What is No it is not. I know this by using the vertical line test.
200
Define Domain and Range.
What is Domain is the set of x values and the Range is the set of y values.
300
Find g(x) = x^2 + 1 for g(t) - 4
What is g(t) - 4 = t^2 - 3
300
Solve the equation y = 2x - 1, given the domain, {-3,-1,0,2}
What is {(-3,-7), (-1,-3), (0,-1), (2,3)}
300
Which graph matched the following statement: x-intercept (2,0) and the y-intercept (0,-4).
What is Graph A
300
Determine if the relation is a function. {(2,1), (6,-3), (-2,5), (4,-3)}
What is Yes, it is a function.
300
What is a relation?
What is a set of ordered pairs.
400
Find h(y) = 3y - 7 for h(2m - 5).
What is h(2m-5) = 6m - 22
400
Solve the equation 2y = x + 2, given the domain {-4,-2,0,2}
What is {(-4,-1), (-2,0), (0,1), (2,2)}
400
Find the x and y intercepts for 4x - y = 4.
What is (1,0) and (0,-4).
400
Determine if the relation is a function.
What is No, it is not a function since one x value goes to two different y values.
400
The dependent variable depends on...
What is the Independent variable, or the Domain.
500
Find a(k) = k^2 - 2k for a(-4) + 6.
What is a(-4) + 6 = 30
500
Find the solution set for 2x + 2y = 6, using the replacement set, {(3,0), (2,1), (-2,-1), (4,-1)}
What is {(3,0), (2,1), (4,-1)}
500
Find the x and y intercepts for 4x - 7y = 14.
What is (3.5,0) and (0,-2).
500
In function notation, what does x and f(x) represent?
What is x represents the Domain and f(x) represents the Range.
500
What does mapping illustrate?
What is each value of x being paired with a y value. It also shows if a relation is a function.
