Evaluating functions
Evaluating a function involves calculating the output value (dependent variable) for a given input value (independent variable). This is done by substituting the input value into the function and simplifying to find the corresponding output value.
The input value is typically denoted by a variable (such as x) in the function, and the output value is represented by f(x) or y.
The process of evaluating functions is important for understanding how functions behave for different input values, solving equations involving functions, and analyzing real-world situations.
To evaluate a function at a specific value of the input variable, simply substitute the input value into the function expression and simplify to find the output value.
Examples;
Function: f(x) = 3x + 2
Function: h(x) = 2x^3 + x - 4
