A U B is the set of elements which are in A, in B, or in both A.
Since,
A = {2, 3, 6}
B = {2, 4, 5, 7}
To find A U B, we have to write all numbers that are in A and/or in B. The number that are in both sets must not be written again.
A U B = {2, 3, 6, 4, 5, 7}
Writing then in acending order:
A U B = {2, 3, 4, 5, 6, 7}
Answer: A U B = {2, 3, 4, 5, 6, 7}.

Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
