| Description: This is a real world example of a parabola because its shaped like a parabola and its shaped like a parabola because that's the way it was grown. Now, we know that a parabolic shape must have a quadratic function, therefore an equation in standard form of f(x)=ax2+bx+c. To find an equation for the parabolic shape of the banana, we need to find the values of a, b, and c. From the banana picture above, we can see that a quadratic function is able to model the banana quite accurately, with a=0.1, b=0, and c=0. Therefore, the equation is f(x)=0.1x2.
