Evaluate the function f(x) = - x^2 - 3 at the given value of the variable.
a. f(2)
b. f(-4)

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

(x) - (y) = (1 + 4i)
