Quizizz: 3-2 Writing Linear Functions

How do you read 

 $f\left(x\right)$  ?

• f x

• f of x

• f parenthesis x

• f times x

 $f\left(x\right)$  

is the same thing as ______.

• y

• x

• input

• an equation

How would you write

 $y=2x-3$  in function notation?

•  $y=2x-3$  
  

•  $f=2x-3$  

•  $f\left(x\right)=2x-3$  
  

Translate the function notation into a coordinate point.

 $f\left(-1\right)=5$  

•  $\left(-1,5\right)$  

•  $\left(1,5\right)$  

•  $\left(5,1\right)$  

•  $\left(5,-1\right)$  

Translate the coordinate pair into function notation.

 $\left(0,8\right)$  

•  $f\left(0\right)=8$  

•  $f\left(0\right)=-8$  

•  $f\left(8\right)=0$  

•  $f\left(-8\right)=0$  

Write a linear equation in slope-intercept form using function notation.

• f(x) = 2x + 2

• f(x) = 2x - 2

• f(x) = x + 2

• f(x) = 3x - 2

Write a linear equation in slope-intercept form using function notation.

• f(x) = 6x - 1

• f(x) = 6x + 1

• f(x) = -x + 6

• f(x) = 2x -1

Look at the graph. Write down the equation for the line using function notation.

• f(x) = - x + 3

• f(x) = 4x + 3

• f(x) = ¹/₄ x + 3

• f(x) = - 4x + 3

Write a linear equation in slope-intercept form using function notation.

• f(x) = 3x - 3

• f(x) = -3x + 3

• f(x) = -3x - 3

• f(x) = 3x + 3

Which graph represents the equation  $f\left(x\right)=4x-1$  

• 
•
