3. The vertices of triangle JEN are J(2, 10), E(6,4), and N(12, 8). Use coordinate geome-
try to prove that triangle JEN is an isosceles
right triangle

I need help with this I need work shown out and need to graph it

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
