Math Problem Statement

Graph the function f(x) = 8 * 3^x for x = 0, 1, 2.

Solution

The function given is f(x)=83xf(x) = 8 \cdot 3^x. Here's how we calculate f(x)f(x) for x=0,1,2x = 0, 1, 2 and graph the function:

  1. Calculate f(x)f(x) for each value of xx:

    • For x=0x = 0: f(0)=830=81=8f(0) = 8 \cdot 3^0 = 8 \cdot 1 = 8

    • For x=1x = 1: f(1)=831=83=24f(1) = 8 \cdot 3^1 = 8 \cdot 3 = 24

    • For x=2x = 2: f(2)=832=89=72f(2) = 8 \cdot 3^2 = 8 \cdot 9 = 72

  2. Fill in the table:

    xxf(x)f(x)
    08
    124
    272
  3. Graph the points (0,8)(0, 8), (1,24)(1, 24), and (2,72)(2, 72):

    • Mark these points on the provided graph grid.
    • Since the function f(x)f(x) is exponential, connect the points smoothly in an upward curve as xx increases.

Let me know if you'd like a step-by-step guide for plotting or further details on exponential graphs!

Here are 5 related questions for you to explore:

  1. What happens to f(x)f(x) as xx becomes negative?
  2. How does the base of the exponential, 33, affect the growth rate?
  3. What would the graph look like if the equation were f(x)=82xf(x) = 8 \cdot 2^x?
  4. What is the domain and range of f(x)f(x)?
  5. Can you explain how the multiplier 88 changes the graph compared to f(x)=3xf(x) = 3^x?

Tip: Exponential functions grow faster as the base increases, so understanding base effects can help predict graph behavior!
