area = 2x² + 7x - 4

the area (A )  of a rectangle = length × width

A = (2x - 1 )(x + 4 ) ← expand using FOIL

   = 2x² + 8x - x - 4 = 2x² + 7x - 4

Write whether the scenario represents a linear function or an exponential function? Explain why.
Ad libitum [116K]
The scenario represents a linear function. The rate is at a constant increase therefore it is linear.

Linear because it’s a constant rate

Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function

Exponential since it increases by a multiplicative rate. It’s not constant
