Capitolo 3, Problema 72
Use the graph of g to solve Exercises 71–76.
Find g(2)
Guida verificata passo dopo passo1
Identify the function g on the graph, which is represented by the red line with points marked.
Locate the x-value of 2 on the horizontal axis (x-axis).
From x = 2, move vertically upwards or downwards until you reach the point on the graph of g.
Determine the y-coordinate of the point on the graph directly above or below x = 2. This y-coordinate is the value of g(2).
Write the value of g(2) as the y-coordinate found in the previous step.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Function Notation
Function notation, such as g(2), represents the output value of the function g when the input is 2. It is a way to denote the relationship between input values (domain) and output values (range) in a function.

Interval Notation
Reading a Graph of a Function
To find g(2) from a graph, locate the input value 2 on the x-axis, then find the corresponding point on the graph. The y-coordinate of this point is the value of g(2). This process helps visualize how the function behaves.

Coordinate Plane and Points
The coordinate plane consists of an x-axis (horizontal) and y-axis (vertical). Points on the graph are represented as (x, y), where x is the input and y is the output. Understanding how to interpret these points is essential for analyzing functions.
