Create a *continuous* function that contains three pieces: one that is a sine curve, one that is a square root graph, and one that is a parabola. Write the function using correct notation. 3-10 HW eTool (Desmos). Homework Help ✎

To be continuous at a point,

1) the limit must exist (agree from the left and the right)

2) the value must exist (be finite)

3) the limit must agree with the value.

If you choose to use the parent graphs, find the location of points that two of them share:

For example:

These *x*-values will give you possible boundary points for your piecewise function.

Arrange the three functions in a way that will make a continuous piecewise graph, meeting at boundary points.

Use the eTool below to create the piecewise function.
