Write the equation and find the foci of the ellipse with the given vertices. (1, 2), (1, -4), (-2, -1), and (4, -1)
Help I need the equation of the eclipse and the foci? Will give brainliest

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
