| Linear and Nonlinear Functions | ||
| #1 | What kind of function is this y=x4 |
Nonlinear |
| #2 | Is this a linear or nonlinear function? y=4x+7 |
It is linear |
| #3 | Is this linear or nonlinear?
|
Nonlinear |
| #4 | Why is one line linear and one line nonlinear?
|
One line is linear because is is a straight line. The other line is nonlinear because it is not a straight line. |
| #5 | Is the equation linear or nonlinear? 4y=x+20 |
The equation is linear |
| Defining a Linear Function Rule | ||
| #1 | Give a real world situation that matches this function. y=2x+10 |
Example: Your mom lets you gives 10 dollaors and your allowance $2 dollars a day. |
| #2 | A box office is selling concert tickets for $6 each. What is the function rule? p for the price and t for the ticket. |
p=6t |
| #3 | Your neighbor is making cupcakes and she sarted with 15 dollars for change and gets 1 dollar every minute. What is the function rule? |
y=x+15 |
| #4 | A gardener used a hose to refill the tank when it reaches 6 gallons. The hose filled the tank at a rate of 7 gallons per minute. What is the linear function rule? |
y=7x+6 |
| #5 | A model train passes its model depot at time=0. After 3 minutes, the train has traveled a distance of 132 ft along the track. What is the linear function rule? |

| #4 | Whats the answer? 102x+4x+209x+-4x+-10x |
301x |
| #5 | What is an initial value? |
An initial value is the place in which the line cross the x-axis |
| Final Question | |
How can you tell if the graph is a function? |
You can tell by using the horizontal line test. |
