​Domain is the x-value of the graph.

​The x-values starts at -6 and ends at 3.



Therefore the domain is -6 ≤ x ≤ 3

In WORDS: All real numbers greater than or equal to -6 and less than or equal to 3


You ALWAYS go left to right!

​Domain with ARROWS!

Domain ONLY cares about the left and right direction!

​Any arrow pointing RIGHT means GREATER THAN. x > -3

​Any arrow pointing LEFT means LESS THAN. x < -3

Multiple Choice

Which of the inequalities below best describes the domain of the function shown on the graph?

• -2 ≤ x ≤ 2
• -5 ≤ x ≤ -3
• -2 ≤ x ≤ 3
• -5 ≤ x ≤ 3

Multiple Choice

Find the domain of the graph below.

• -2 ≤ x < 4

• -3 < x ≤ 4

• -2 ≤ y < 4

• -3 < y ≤ 4

Multiple Choice

The domain of this function is ?

• $$x<2$$

• $$x>2$$

• $$y>-2$$

• $$y<-2$$

​Range is the y-value of the graph.

​The y-values starts at 1 and ends at 7.


Therefore the range is 1 ≤ y ≤ 7

OR 1 ≤ f(x) ≤ 7

In WORDS: All real numbers greater than or equal to 1 and less than or equal to 7


You ALWAYS go bottom to top

Range with ARROWS!

Range ONLY cares about the up and down direction!

​Any arrow pointing UP means GREATER THAN. y >

​Any arrow pointing DOWN means LESS THAN. y <

Multiple Choice

Function f is graphed to the right. What is the range of f?

• -2 ≤ x < 4

• -2 < x ≤ 4

• -3 ≤ y < 3

• -3 < y ≤ 3

Multiple Choice

Find the range of the graph below.

• -2 ≤ x < 4

• -3 < x ≤ 4

• -2 ≤ y < 4

• -3 < y ≤ 4

Multiple Choice

A student rode a bike from school to a recreation center. The graph shows the student’s distance in miles from the recreation center after riding the bike for x miles. What is the range of the situation?

• All real numbers greater than or equal to 0 and less than or equal to 28

• All real numbers greater than or equal to 0 and less than or equal to 9

• All real numbers less than 28

• All real numbers less than 9

You must make an 80%+ on the assignment in order to retest!
