Math Problem Statement

If the points (-5, -2) and (3, 6) lie on the graph of an odd function f, then what do f(5) and f(-3) equal?

Solution

To solve this problem, let's understand what it means for a function to be odd. If f(x)f(x) is an odd function, it satisfies the property:

f(x)=f(x)f(-x) = -f(x)

The points given are (5,2)(-5, -2) and (3,6)(3, 6).

Solution Steps:

  1. Find f(5)f(5):

    • Since (5,2)(-5, -2) is a point on the graph of ff, we have f(5)=2f(-5) = -2.
    • Using the property of odd functions, f(5)=f(5)f(5) = -f(-5).
    • Therefore, f(5)=(2)=2f(5) = -(-2) = 2.
  2. Find f(3)f(-3):

    • Since (3,6)(3, 6) is a point on the graph of ff, we have f(3)=6f(3) = 6.
    • Using the odd function property, f(3)=f(3)f(-3) = -f(3).
    • Therefore, f(3)=6f(-3) = -6.

Answer:

f(5)=2andf(3)=6f(5) = 2 \quad \text{and} \quad f(-3) = -6

Here are five related questions to explore further:

  1. What defines an even function, and how does it differ from an odd function?
  2. If the function were even instead of odd, what would the values of f(5)f(5) and f(3)f(-3) be?
  3. How does symmetry play a role in identifying odd and even functions on a graph?
  4. Can a function be both odd and even? If so, what type of function would that be?
  5. How would we determine values for a function that is neither odd nor even?

Tip: Remember, odd functions are symmetric with respect to the origin, while even functions are symmetric about the y-axis.
