Quizplus · Accepted Answer

The operation $(f \cdot g)(x)$ means to multiply the functions $f(x)$ and $g(x)$ together. So, $(f \cdot g)(x) = f(x) \cdot g(x) = x \cdot (2x - 7) = 2x^2 - 7x$.

Provide an Appropriate Response f(x)=xf ( x ) = xf(x)=x And g(x)=2x−7g ( x ) = 2 x - 7g(x)=2x−7

Provide an Appropriate Response $f ( x ) = x$ And $g ( x ) = 2 x - 7$
