What is the domain for the Linear Piece of f(x)?

• Not enough information given

Over what interval is this function constant?

• -5 < x < ∞

• -3 < x < 4

• 4 < x < ∞

• -5

For a given​ piecewise-defined function, the pieces of the function are defined for intervals of the​ domain, x≤−1 and x>−1.

Explain how you could find the​ y-intercept for the function over the intervals x≤−1 and x>−1​?

The​ y-intercept is included in the piece of the function that crosses the​ ​ (a)   The piece for the interval ​ (b)  

• y-axis

• x-axis

• x>-1

• x≤-1

Match the graph with the correct equation.

• The middle of the graph

Which of the following is the decreasing interval of the function?

Where is the function decreasing?

• A

  (−∞ < x < −2.55) U (0 ≤ x ≤ 2.55)

• B

  (∞ < x < −6.25) U (36 < x < −6.25)

• C
