**Across**

4. If there is an interval containing *a* for which *f(a)* is less than or equal to *f(x)* for all *x* in the interval, the value *f(a)* is one of these.

7. A kind of function whose graph is U-shaped

9. A kind of function whose graph is a straight line

10. The word used to describe functions whose graphs are symmetric about the origin

11. The word used to describe functions whose graphs are symmetric about the *y*-axis

13. Values of *x* for which *f(x)=0*

**Down**

1. Transformations of this type, like stretches and shrinks, cause a distortion.

2. The collection of ordered pairs *(x, f(x))* such that *x* is in the domain of *f*

3. Horizontal shifts, vertical shifts and reflections are these sorts of transformations.

5. Points at which the graph intersects the axes

6. The direction that a graph is shifted when you add a constant to *y=f(x)*.

8. A kind of function whose graph is S-shaped

12. The graph of *f(x+3)* is the same as the graph of *f(x)* shifted three units in this direction.
