b. g (ƒ (2))

Guida verificata passo dopo passo

Identify the value of $ f(2) $ from the graph of $ f(x) $.

Substitute $ f(2) $ into the function $ g(x) $ to find $ g(f(2)) $.

Locate the value of $ g(f(2)) $ on the graph of $ g(x) $.

Verify the corresponding $ y $-value on the graph of $ g(x) $ for the input $ f(2) $.

Conclude the process by confirming the value of $ g(f(2)) $ from the graph.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Function Composition

Function composition involves combining two functions where the output of one function becomes the input of another. In this case, g(f(2)) means you first evaluate f at 2, and then take that result and use it as the input for g. Understanding how to properly execute this process is crucial for solving the problem.

Evaluating Functions

Evaluating a function at a specific point requires substituting the input value into the function's equation or graph. For f(2), you would find the value of the function f at x = 2, which can be done by looking at the graph of f. This step is essential before proceeding to the next function in the composition.

Graph Interpretation

Interpreting graphs is vital for understanding the behavior of functions visually. You need to analyze the graphs of f and g to find the corresponding values at specific points. This skill allows you to extract necessary information from the graphs to evaluate the functions accurately.
