f(x)=2x.

Short Answer

Expert verified

Domain of the function is(-∞,∞).Range of the function is(-∞,∞).

Step by step solution

01

Step 1. Given Information

Given that the linear function asf(x)=2x.

02

Step 3. Linear function

It is confirmed that the given function is linear. The slope ism=2.The y-intercept is(0,0).

03

Step 3. Graph of the function

The graph can be drawn using slope and intercept.

04

Step 4. Domain and Range

Because given function is a constant linear function, domain of constant linear function is all real numbers. Domain of the given function is(-∞,∞).Because given function is a constant linear function, range of linear function is just a constant value. Range of the function is (-∞,∞).
