Let U = {1, 2, 3, 4, 5, 6, 7, 8), A = {2, 4, 6}, B = {1, 2, 5, 8}, and C = {3, 5, 7}. Find the following (Use the roster method to write the set Enter EMPTY or for the empty set.)

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
