Let F and G be functions from the set of all real numbers to itself. Define the product

Chapter 7, Problem 15

(choose chapter or problem)

Let F and G be functions from the set of all real numbers to itself. Define the product functions \(F \cdot G: \mathbf{R} \rightarrow \mathbf{R}\) and

\(G \cdot F: \mathbf{R} \rightarrow \mathbf{R}\) as follows: For all \(x \in \mathbf{R}\),

\((F \cdot G)(x)=F(x) \cdot G(x)\)

\((G \cdot F)(x)=G(x) \cdot F(x)\)

Does \(F \cdot G=G \cdot F\)? Explain.

Text Transcription:

F cdot G: mathbf R rightarrow mathbf R

G cdot F: mathbf R rightarrow mathbf R

x in mathbf R

(F cdot G)(x)=F(x) cdot G(x)

(G cdot F)(x)=G(x) cdot F(x)

F cdot G=G cdot F
