## How do you solve linear functions in FX?

Solving Linear Functions

- Substitute the value of f(x) into the problem. In this case:
- Isolate the variable. In this case, you add 1 to both sides to isolate the variable term by using the opposite operation to move the constant term across the equal sign.
- Continue to isolate the variable.
- Simplify.

**How do you calculate a linear function?**

The linear function formulas are: y = mx + b (slope-intercept form)…

- (x, y) in every equation is a general point on the line.
- (x1,y1) ( x 1 , y 1 ) is any fixed point on the line.
- m is the slope of the line.
- (a, 0) and (0, b) are the x-intercept and y-intercept respectively.
- A, B, and C are constants.

**What does F 3x mean?**

If g(x) = f (3x): For any given output, the input of g is one-third the input of f, so the graph is shrunk horizontally by a factor of 3.

### How do you find FX on a linear graph?

Since two points determine a line, draw a line through these two points with a straightedge to complete the graph. Linear functions have the form f(x)=mx+b, where the slope m and b are real numbers. To find the x-intercept, if one exists, set f(x)=0 and solve for x. Since y=f(x) we can use y and f(x) interchangeably.

**What kind of transformation is F 3x?**

Translations and the Effect on Domain & Range

Graph | Translation | Domain |
---|---|---|

y=f(x)-2 | down 2 | (-2,5) |

y=3f(x) | multiply each y by 3 | (-2,5) |

y=f(3x) | divide each x by 3 | (-2/3,5/3) |

y=2f(x-3)-5 | multiply each y by 2 and subtract 5; add 3 to every x | (1,8) |
