Function Transformations

This concept refers to the methods used to modify the graph of a function by applying systematic changes, such as shifts, reflections, stretches, or compressions. In the transformation from f(x) to g(x), the original exponential function is altered by combining two such operations.

Vertical Reflection

A vertical reflection involves multiplying the function by -1. This change flips the graph over the horizontal axis, turning points above the axis into corresponding points below it. In the expression g(x) = 3 - 2^x, the term -2^x indicates that the graph of f(x) = 2^x has been reflected vertically.

Vertical Translation

This transformation shifts the entire graph of a function upward or downward along the y-axis. Adding a constant term adjusts the vertical position without altering the shape of the graph. In g(x) = 3 - 2^x, the addition of 3 after the vertical reflection lifts the reflected graph upward by 3 units.

Exponential Functions

Exponential functions are those in which the variable appears in the exponent, exhibiting rapid growth or decay. The function f(x) = 2^x is a classic example, and understanding its behavior is essential before applying transformations such as reflections and translations, as seen in g(x) = 3 - 2^x.
