Question A rectangle has a length represented by the function f(x)=x and a width represented by the function g(x)=x+3 where both functions are in feet. Calculate (f⋅g)(x) and state what it represents. (1 point) Responses
(f⋅g)(x)=x2+3x ; It represents the perimeter of the rectangle in feet
(f⋅g)(x)=x2+3x ; It represents the area of the rectangle in square feet.
(f⋅g)(x)=4x+6 ; It represents the perimeter of the rectangle in feet.
(f⋅g)(x)=4x+6 ; It represents the area of the rectangle in square feet.
(f⋅g)(x)=x*(x+3) = x^2 + 3x
Therefore, (f⋅g)(x)=x^2 + 3x represents the area of the rectangle in square feet.
