• 

State the range of the above piecewise function?

• R: y = All real numbers
  
  

• None of these are correct.

State the domain of the following Piecewise Function:

• D: x = All real numbers

• D: y = 2 or  y < 0

• None of these are correct.

State the domain of the above piecewise function:

• D: x = All real numbers

• none of these are correct.

Evaluate the function when x = 4

• f(4) = 2(4) - 5 = 3

• f(4) = 2(4) - 5 = -1

• f(4) = ½(4) + 1 = 3

• f(4) = 4

State the range of the following Piecewise Function:

• R: y = All real numbers

• None of these are correct.

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

• 1≤ x ≤ 4

• 1 < x < 4

• 1≤ y ≤ 4

• 1 < y < 4
