We select 3 balls without replacement from a urn containing 4 red balls, 3 yellow balls and 3 blue balls. Assuming equally likely outcomes, find the probability that we do not see all three colors in the three selected balls. Simplify your answer to a fraction a b .

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
