A square pen that is surrounded by a fence is divided into 2 rectangular regions by adding a new fence that connects the midpoints of 2 opposite sides. By what percent has the total length of fencing been increased?

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

25% is the answer
