Describe the set of antiderivatives of ƒ(x) = 1

검증된 단계별 안내

Recognize that the antiderivative of a function ƒ(x) is a function F(x) such that the derivative of F(x) equals ƒ(x). In this case, we are given ƒ(x) = 1.

Recall the basic rule of integration: the antiderivative of a constant c is c * x + C, where C is the constant of integration. Here, the constant c is 1.

Apply the rule to find the antiderivative of ƒ(x) = 1. The result is F(x) = x + C, where C represents an arbitrary constant.

Understand that the set of antiderivatives of ƒ(x) = 1 is represented by the family of functions F(x) = x + C, where C can be any real number.

Conclude that the set of antiderivatives is infinite, as it depends on the value of the constant C, which can vary freely.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Antiderivative

An antiderivative of a function f(x) is another function F(x) such that the derivative of F(x) equals f(x). In other words, if F'(x) = f(x), then F(x) is an antiderivative of f(x). Antiderivatives are essential in calculus as they are used to find the area under curves and solve differential equations.

Constant Functions

The function f(x) = 1 is a constant function, meaning it has the same value (1) for all x in its domain. The antiderivative of a constant function is a linear function, which can be expressed as F(x) = x + C, where C is a constant. This reflects the fact that the slope of the constant function is zero, leading to a linear increase in the antiderivative.

Family of Antiderivatives

The set of all antiderivatives of a function forms a family of functions that differ only by a constant. For the function f(x) = 1, the family of antiderivatives can be expressed as F(x) = x + C, where C represents any real number. This indicates that there are infinitely many antiderivatives, each corresponding to a different vertical shift of the linear function.
