35:47 The area of the two rectangles is given by the functions:

Area of Rectangle A: f(x) = 4x2 + 6x

Area of Rectangle B: g(x) = 3x2 – x

Which function represents the difference, h(x) = f(x) – g(x), in the areas of the rectangles shown?

x^2+7x if you are asked to find the difference of a function f and function g

Step-by-step explanation:

We are asked to A-B or f(x)-g(x).

(4x^2+6x)-(3x^2-x)

4x^2+6x-3x^2+x

The like terms I'm going to pair up.

4x^2-3x^2+6x+x

1x^2          +7x

x^2            +7x
