Evaluating Quadratic Functions: Example 10

Topic

Quadratics

Description

Evaluating a function means determining the output value (y) for a given input value (x). In function notation, we write f(x) to represent the function, and f(a) represents the output value when x = a.

For a quadratic function in standard form f(x) = ax² + bx + c, evaluating the function involves substituting a specific value for x and calculating the result using the given coefficients a, b, and c.This final example evaluates f(x) = -10x² - 5x - 10 at x = 3. Substituting 3 for x gives: f(3) = -115.
