1-69.

Much of this course will focus on change. Examine two ways a line changes:

1. Sketch $f(x) = 2x + 3$. Find $f(0)$, $f(1)$, $f(2)$, and $f(3)$. How are the function values changing as $x$ increases?

How do the $f(x)$ values change as $x$ increases? Do these values increase, decrease or stay constant?

2. Sketch $f(x) = −3x + 10$. Find $f(0)$, $f(1)$, $f(2)$, and $f(3)$. How are the function values changing as $x$ increases?

How do the $f(x)$ values change as $x$ increases? Do these values increase, decrease or stay constant?

Use the eTool below to makes changes to the $x$ values.
