Chapter 3: Q. 345 (page 344)

(a) Graph the function $f (x) = - 2 x + 2$ .
(b) State its domain and range. Write the domain and range in interval notation.

Short Answer

Expert verified

Graph of the function is

$D o m a i n : (- \infty, \infty) R a n g e : (- \infty, \infty)$

Step by step solution

Given Information

The equation of the function is

$f (x) = - 2 x + 2$

Part(a) Step 1: Graph the given function

Function f(x) is in the form of $f (x) = m x + b$

where m is the slope and b is the y intercept .

$f (x) = - 2 x + 2 s l o p e = - 2 y i n t e r c e p t = 2$

Plot the y intercept (0,2).

Now use the slope =-2

Move 2 unit down and 1 unit to the right .

Plot the point at (1,0). Connect the points by a line .

The graph of the function is

Part(b) Step 1: Domain and Range

Domain is the set of x values for which the function is defined.

The graph is defined for all x values .

Range is the set of y values for which the function is defined. The graph is defined for all y values .

Interval notation :

$D o m a i n : (- \infty, \infty) R a n g e : (- \infty, \infty)$
