Questions & Step-by-Step Solutions
Determine the family of curves represented by the equation y = e^(kx) for varying k.
Step 1: Understand the equation y = e^(kx). This means y is equal to the exponential function e raised to the power of k times x.
Step 2: Identify what k represents. The variable k is a constant that can take different values, which affects the shape of the curve.
Step 3: Recognize that for different values of k, the curve will grow at different rates. If k is positive, the curve will rise steeply; if k is negative, the curve will fall.
Step 4: Realize that all these curves (for different k values) are part of the same family of curves, known as exponential curves.
Step 5: Conclude that the family of curves represented by the equation y = e^(kx) includes all the curves for varying values of k.
Exponential Functions – The equation y = e^(kx) describes exponential growth or decay depending on the value of k.
Parameter Variation – The parameter k affects the steepness and direction of the curve, illustrating how families of curves can be generated by varying parameters.
