step-by-step explanation:

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

many reason,

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

all of them are elements inside set of real numbers since none of them appears to have complex number form.
