In Exercises 65–70, use the graph of f to find each indicated function value.
f(-2)

Key Concepts

Function Value

The function value, denoted as f(x), represents the output of a function for a given input x. In this context, finding f(-2) means determining the y-coordinate of the graph at x = -2. This is essential for understanding how to evaluate functions graphically.

Graph Interpretation

Interpreting a graph involves analyzing the plotted points and curves to extract information about the function. This includes identifying key features such as intercepts, slopes, and specific function values at given x-coordinates, which is crucial for answering the question about f(-2).

Coordinate System

A coordinate system provides a framework for locating points in a plane using pairs of numbers (x, y). In this case, the x-axis represents the input values, while the y-axis represents the output values of the function. Understanding this system is vital for accurately reading the graph and finding the desired function value.
