- 1Is (2, 3) a solution to the equation y = 2x - 1y = 2x - 1
3 = 2(2) - 1
3 = 4 - 1
3 = 3
Yes - 2Is this relation a function? Explain why or why not . (0,1) (1,2) (2,3) (3,4) (4,4)Yes, this relation is a function because every input has exactly one output.
- 3—Linear;
Not a function - 4What are the input values?The x values
- 5What are the characteristics of a linear graph?A straight line
- 6How do you know if a GRAPH is a function?It passes the Vertical Line Test
- 7What are the output values?The y values
- 8—Linear;
Not a function
- 9Is this relation a function? Explain why or why not. (-3,-1) (-2,0) (-1,3) (-1,0) (0,-1)No, this relation is not a function because the ordered pair (-1,3) and (-1,0) have the same input but different outputs.
- 10What does it mean to be a function?Each input has only one output
- 11—Nonlinear
- 12What are the characteristics of nonlinear in a graph?Graph is NOT a straight line
- 13—Decreasing
- 14—Linear;
Function
- 15What are the characteristics of a nonlinear table?Both the x and y values do not change by a constant amount
- 16—Nonlinear;
Function
- 17What are the input values in the following: {(1, 10) (2, 12) (3, 14) (4, 16)}{1, 2, 3, 4}
- 18—Linear
- 19What does a line with the equation x = -8 look like?A vertical line passing through the x-axis at (-8,0)
- 20—Linear;
Function
- 21—Increasing
- 22—Nonlinear
- 23What are the characteristics of a linear equation?The equation has the variables in separate terms and all the variables have an exponent of 1
- 24What does the graph of a line with the equation y = 2 look like?A horizontal line passing through the y-axis at (0,2)
- 25Is this relation a function? Explain why or why not. (10,1) (11,6) (12,11) (13,16) (14,21)Yes, this relation is a function because every input has exactly one output.
- 26Is the following equation linear or nonlinear? x = 7Linear
- 27—Linear;
Function
- 28What are the output values in the following: {(1, 10); (2, 12); (3, 14)}{10, 12, 14}
- 29Is the following equation linear or nonlinear? y = -2x + 7Linear
- 30—Nonlinear;
Not a function
- 31—From x=0 to x=8 and from x=12 to x=20
- 32What are the characteristics of nonlinear in an equation?The equation does not have the variables in separate terms or a variable has an exponent other than 1
- 33What are the characteristics of a linear table?Both the x and y values change by a constant amount
- 34Is this relation a function? If not, explain why. (-2,-2) (2,-1) (3,0) (5,3) (5,4)No, this relation is not a function because the ordered pair (5,3) and (5,4) have the same input but different outputs.
- 35What is the vertical line test?A visual method of determining whether a graph is a function by visualizing whether any vertical lines would intersect the graph at more than one point or not
- 36Increasing Linear FunctionA function whose graph is a straight line that rises from left to right.
- 37Is (3, 2) a solution to the equation y = 2x - 1y = 2x - 1
2 = 2(3) - 1
2 = 6 - 1
2 = 5
No - 38Decreasing Linear FunctionA function whose graph is a straight line that falls from left to right.
