2points in the ellipse shown below, the red line segment is called the o a. major axis b. radius a o c. diameter o d. minor axis

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

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

it would open into a square depending on the type of envelope i’m not sure about the second part
