The piecewise function is of a jogger’s speed over time. For what interval does this runner reach their maximum speed?

• 0min – 2min

• 2min

• 18min – 19min

• 19 min

What is the boundary line for the given piecewise function?

• x=-2

• x=-4

• 2

• 3

• 4

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

Determine the x-intercept(s) of this function.

• x= -6, x= 1/2

• x= -6

• x= 1/2

• No x-intercepts exist

Match the graph with the correct equation.
