What is the family of curves represented by the equation y = e^(kx)?
Correct Answer: y = e^(kx) represents a family of exponential functions.
- Step 1: Understand the equation y = e^(kx). Here, 'e' is a constant (approximately 2.718), and 'k' is a variable that can change.
- Step 2: Recognize that 'k' affects the shape of the curve. If 'k' is positive, the curve will rise as x increases (exponential growth).
- Step 3: If 'k' is negative, the curve will fall as x increases (exponential decay).
- Step 4: Realize that different values of 'k' create different curves, but they all share the same basic shape (exponential).
- Step 5: Conclude that the equation y = e^(kx) represents a family of curves, each defined by a specific value of 'k'.
