Functions

The rate of change is the same thing as...

• y-intercept

• slope

• y

• x

Math the graphs with what is a true description.

• Matches with a relation where each input has exactly one output

• Linear Function

• Matches with a relation that forms a curve that increases at an increasing rate when graphed

• Exponential Function

• Matches with a relation that forms a straight line when graphed

• Nonlinear Function

• Matches with a relation that does not form a straight line when graphed

• Not a function

• The x-values have more than one y-value

• Function

A function is a type of rule in which each ​ (a)   results in exactly one ​ (b)   .​

• input
• output
• linear
• nonlinear
• straight line

In the equation y = mx + b, what do the following terms represent?

• slope

• y

• output

• b

• input

• x

• y-intercept (initial value)

• m

Output is represented by​ (a)   and input is represented by ​ (b)   .

• y
• x

Which of the following are functions and which are not functions?

• Not a function b
