What is the domain of the graph?
Remember:  Domain is x

• 1≤ x ≤ 4

• 1 < x < 4

• 1≤ y ≤ 4

• 1 < y < 4

What is the RANGE of this function?

• -8≤y≤8

• -8≤x≤8

• All Real Numbers

• -1<y<1

What is the domain of the linear function

y = -4x + 3?

• {-4}

• {3}

• all real numbers

Milan has a car that gets 30 miles per gallon. Her car has a 12 gallon tank. The function f(x) = 12(30) - 60x models how long Milan can drive until her tank is empty at 60 miles per hour. What are the domain and range of this situation?

• Domain: 0 < x < 360

  Range: 0 < y < 12

• Domain: 0 < x < 6

  Range: 0 < y < 360

• Domain: all real numbers

  Range: all real numbers

• Domain: 0 < x < 30

  Range: 0 < y < 60
