What is the definition of a function?
A relation where each input has one and only one output.
100
Evaluate y = 2x +1 when x = -3
y = -5
100
A table of values for a linear function is given. Fill in the missing value.
x -1 0 1
y 3 8 ?
y = 13
100
What is the slope of y=2x+4?
m=2
100
Based on the graph of function,
What is y when x = 2?
y = 3
200
Yes
200
Evaluate y= x2 + x + 1 when x = -5
y = 21
200
A table of values for a linear function is given. Fill in the missing value.
x -1 0 1
y 3 -2 ?
y = -7
200
What is the slope of y + 2x = 4?
m= -2
Must get in Slope-intercept form first.
y = -2x + 4
200
Based on the graph of function,
f(-5)=?
y = 0
300
Is this a function and why?
No because x=8 has two outputs (3 and -3)
300
Evaluate y = x2 - 2 when x = -2
y = 2

A table of values for a linear function is given. Fill in the missing value.
x 2 3 5
y 2 1 ?
y = -1
300
What is the y intercept of y = -3x - 5?
b= -5
300
Based on the graph of the function, what is f(4)?
y = -2
400
Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2, has two different outputs (y)
400
Evaluate y = 4x2 - 1 when x= -2
y = 15
400
A table of values for a linear function is given. Fill in the missing value.
