Chapter 3: Q 355. (page 344)

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

f(x)=-2x.

Short Answer

Expert verified

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

Step by step solution

01

Step 1. Given Information

The given linear function isf(x)=-2x.

02

Step 2. Slope and Intercept

Its in the form of Slope-Intercept. Slope and y-intercept arem=-2,(0,0).

03

Step 3. Graph of the function

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

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