# Knowing the type of graph by looking at the equation, makes it very easy to sketch a graph.

## The following is a list of examples of a variety of graphs.

## Equation Degree Name Shape Description

### 1. * linear straight line / if x is +, **\ if x is -*

*2. quadratic Parabola opens up if x is +, ** opens down if x is -*

*3. cubic wavy line falls to the left and rises to the right if x is +, falls to the right and rises to the right if x is -*

*4. quadratic parabola opens to the right if y is +. opens to the left if y is -*

*5. absolute value v shaped upright v if + . **inverted v if -*

### Describe the graph of the given equation.

### a. — the graph is a parabola that opens up

### b. — the graph is a cubic wavy line that falls to the left and rises to the right

### c. — the graph is a straight line that slopes to the left

### d. –the graph is a v that opens up, the vertex is a point on the y-axis that is three units below the x-axis.
