Key Concepts

Function Evaluation

Function evaluation involves substituting a specific input value into the function's expression to compute its corresponding output. This process is fundamental in understanding and analyzing the behavior of functions at particular points.

Function Substitution

Function substitution refers to replacing the variable in a function's formula with an expression or another variable form. It is used to find the output for modified inputs such as negatives, sums with constants, or scaled variables, and is crucial for transforming the function's domain.

Reflection of Functions

Reflection of functions deals with how the graph of a function changes when the sign of its input or output is reversed. Evaluating f(-x) reflects the graph across the y-axis, while computing -f(x) reflects it across the x-axis, highlighting the differences in input and output manipulation.

Horizontal Transformations

Horizontal transformations occur when the independent variable in a function is replaced by an expression like (x + constant) or a multiple of x. These modifications, such as in f(x + 1) or f(2x), result in horizontal shifts or scalings that alter the graph's position and width without changing its overall shape.
