If mZDCE= 4x + 15 and MZECF= 6x -5, find mZDCE.

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

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
