## How do you shift a function up and down?

This is always true: To move a function up, you add outside the function: f (x) + b is f (x) moved up b units. Moving the function down works the same way; f (x) – b is f (x) moved down b units.

**What does it mean to shift a graph?**

Shifts. A shift is a rigid translation in that it does not change the shape or size of the graph of the function. All that a shift will do is change the location of the graph. A vertical shift adds/subtracts a constant to/from every y-coordinate while leaving the x-coordinate unchanged.

### How do you shift a function down?

To translate the function up and down, you simply add or subtract numbers from the whole function. If you add a positive number (or subtract a negative number), you translate the function up. If you subtract a positive number (or add a negative number), you translate the function down.

**Which parameter shifts the graph up or down?**

Informally: Adding a positive number after the x outside the parentheses shifts the graph up, adding a negative (or subtracting) shifts the graph down.

#### How do you scale down a function?

Scaling is a process of changing the shape and size of the graph of the function. Vertical scaling refers to changing the shape and size of the graph of the function along the y-axis and is done by multiplying the function by some constant. The distance of the points on the curve gets farther away from the x-axis.

**How do you move a graph on Desmos?**

You can change a static point to a movable point by clicking and long-holding the icon next to the expression list. A style editor will pop up with different drag options. Another way to create a movable point is to enter a point with a parameter for one or both coordinates.

## What do you call a graph going down?

Decline/fall/drop are all synonyms, and they are all antonyms to rise/increase. All three can be used as a verb or noun, just like their antonyms. Go down is an antonym to go up. The parts of a graph: X-Axis: the horizontal portion of a graph.

**What is it called when a graph flattens out?**

A cumulative curve that increases slowly and flattens out indicates a community that has slowed the spread. So, conveniently, you can apply the phrase “flatten the curve” to the curve of cumulative cases. Note that you do not want the graph of new cases versus time to be flat.
