Math Problem Statement

make a table for this function f(x) = 8x − 3

Solution

Let's create a table for the function f(x)=8x3f(x) = 8x - 3 by choosing a few values of xx, calculating f(x)f(x) for each, and then recording the results.

Table of values for f(x)=8x3f(x) = 8x - 3

xxf(x)=8x3f(x) = 8x - 3
-28(2)3=163=198(-2) - 3 = -16 - 3 = -19
-18(1)3=83=118(-1) - 3 = -8 - 3 = -11
08(0)3=03=38(0) - 3 = 0 - 3 = -3
18(1)3=83=58(1) - 3 = 8 - 3 = 5
28(2)3=163=138(2) - 3 = 16 - 3 = 13

Summary of Values:

  • When x=2x = -2, f(x)=19f(x) = -19
  • When x=1x = -1, f(x)=11f(x) = -11
  • When x=0x = 0, f(x)=3f(x) = -3
  • When x=1x = 1, f(x)=5f(x) = 5
  • When x=2x = 2, f(x)=13f(x) = 13

Would you like more details or have any specific questions?

Here are five related questions to deepen your understanding:

  1. What is the slope of the linear function f(x)=8x3f(x) = 8x - 3?
  2. What is the y-intercept of the function f(x)=8x3f(x) = 8x - 3?
  3. How would the graph of f(x)=8x3f(x) = 8x - 3 look like?
  4. How does the function f(x)f(x) behave as xx \to \infty?
  5. How would the function change if the equation was f(x)=8x+3f(x) = 8x + 3?

Tip: For linear functions like f(x)=8x3f(x) = 8x - 3, the coefficient of xx is the slope, which tells you how steep the line is.
