Capitolo 1, Problema 57

Let f(x) = -3x + 4 and g(x) = -x² + 4x + 1. Find each of the following. Simplify if necessary. See Example 6. ƒ(x + 2)

Guida verificata passo dopo passo
1
Identify the given functions: \(f(x) = -3x + 4\) and \(g(x) = -x^{2} + 4x + 1\).
To find \(f(x + 2)\), substitute every occurrence of \(x\) in \(f(x)\) with \((x + 2)\).
Write the substitution explicitly: \(f(x + 2) = -3(x + 2) + 4\).
Apply the distributive property to expand: \(-3(x + 2) = -3x - 6\).
Combine like terms to simplify: \(f(x + 2) = -3x - 6 + 4 = -3x - 2\).

Concetti chiave

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

Function Notation and Evaluation

Function notation, such as f(x), represents a rule that assigns each input x to an output. Evaluating f(x + 2) means substituting x + 2 into the function in place of x, then simplifying the expression to find the output.

Polynomial Functions

Polynomial functions are expressions involving variables raised to whole number powers with coefficients. Understanding how to manipulate and simplify polynomials, such as linear (f(x) = -3x + 4) and quadratic (g(x) = -x² + 4x + 1), is essential for evaluating and combining functions.
