Review: Zeros of Functions, Slope from a Graph, and SIF

What do zeros (of a function) represent?

• how much you care about functions

• the place that the function crosses the x axis/ the x value that makes the whole function equal to zero

• the place that the function crosses the y axis/ the y value where x=0

• the number zero

Identify the solutions of the graph?
