# If c is a zero of even multiplicity for a function f, then the graph of f ______ the x-axis at c.

**Solution:**

If c is a zero of even multiplicity for a function f, then the graph of f touches the x-axis at c.

For example, let f(x) = (x - 4)^{2}

The zero of f(x) is x = 4 is a value of c which is an even multiple.

Now observe the below graph. We observe that the graph touches the x-axis at x = 4.

## If c is a zero of even multiplicity for a function f, then the graph of f ______ the x-axis at c.

**Summary: **

If c is a zero of even multiplicity for a function f, then the graph of f touches the x-axis at c.
