Math Problem Statement

Linier graphic fuction f(x)=-3x+2 and domain = (-2,-1,0,1,2,3)

Solution

The linear function given is f(x)=3x+2f(x) = -3x + 2. You want to determine the values of the function for the specified domain (2,1,0,1,2,3)(-2, -1, 0, 1, 2, 3).

Let's compute f(x)f(x) for each value in the domain:

  1. For x=2x = -2: f(2)=3(2)+2=6+2=8f(-2) = -3(-2) + 2 = 6 + 2 = 8

  2. For x=1x = -1: f(1)=3(1)+2=3+2=5f(-1) = -3(-1) + 2 = 3 + 2 = 5

  3. For x=0x = 0: f(0)=3(0)+2=0+2=2f(0) = -3(0) + 2 = 0 + 2 = 2

  4. For x=1x = 1: f(1)=3(1)+2=3+2=1f(1) = -3(1) + 2 = -3 + 2 = -1

  5. For x=2x = 2: f(2)=3(2)+2=6+2=4f(2) = -3(2) + 2 = -6 + 2 = -4

  6. For x=3x = 3: f(3)=3(3)+2=9+2=7f(3) = -3(3) + 2 = -9 + 2 = -7

Thus, the corresponding values of the function for each point in the domain are:

f(-2) &= 8, \\ f(-1) &= 5, \\ f(0) &= 2, \\ f(1) &= -1, \\ f(2) &= -4, \\ f(3) &= -7. \end{aligned}$$ ### Table of values: | $$x$$ | $$f(x)$$ | |-----------|------------| | -2 | 8 | | -1 | 5 | | 0 | 2 | | 1 | -1 | | 2 | -4 | | 3 | -7 | Would you like a more detailed explanation or any additional help? Here are 5 related questions to expand on this: 1. How would the graph of this linear function look based on the table of values? 2. What is the slope of the line represented by $$f(x) = -3x + 2$$? 3. Can you determine the $$y$$-intercept from the function's equation? 4. How would the function change if the slope were different, say $$f(x) = 2x + 2$$? 5. What is the domain and range of this function? **Tip:** To graph a linear function, use the slope-intercept form $$f(x) = mx + b$$, where $$m$$ is the slope and $$b$$ is the $$y$$-intercept.
