How do we know when we have a reflection for an exponential function

The video tutorial discusses reflections over the X and Y axes, focusing on quadratics and exponential functions. Quadratics are symmetrical about their axis of symmetry, so reflecting them over the Y axis doesn't change their graph. However, exponential functions are not symmetrical, requiring reflections over both axes. The tutorial explains how multiplying by -1 reflects a function over the X axis and how a negative exponent reflects it over the Y axis. The key takeaway is understanding these reflections without needing graphing technology.

What is the significance of the negative sign in front of the exponential function A to the X?

Describe the effect of reflecting a function over the Y axis and provide an example.
