Chapter 3: Q 356. (page 344)

a) Graph each function. b) State its domain and range. Write the domain and range in interval notation.

f(x)=-3x.

Short Answer

Expert verified

Domain of the given function is(-鈭�,鈭�).Range of the given function is(-鈭�,鈭�).

Step by step solution

01

Step 1. Given Information

The given linear function aref(x)=-3x.

02

Step 2. Slope and Intercept

Slope of the given linear function ism=-3.The y-intercept are(0,0).

03

Step 3. Graph of the function

The graph of the function using slope and intercept can be drawn,

04

Step 4. Domain and range

Because given function is a constant linear function, domain of linear function is just a constant value. Domain of the function is(-鈭�,鈭�).Because given function is a constant linear function, range of linear function is just a constant value. Range of the function is (-鈭�,鈭�).
