Answer:
2D shape comprised of two dimensions that are length and width. As against, a 3D shape incorporates three dimensions that are length, width and height.
Step-by-step explanation:
the given sets are,
D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}
now,
D U E = { 4 , 6, 7 , 8, 9}
and'
E intersection F = E n F = {6 , 7)
thus, the answer is
D U E = { 4 , 6, 7 , 8, 9} and
E n F = {6 , 7)

The first thing we shall be doing here is substituting f(x) into g(x).
Mathematically, that would be written as g(f(x))
= 2(4x-3)-1 = 8x -6 -1 = 8x - 7
Now we shall find g(f(2)) by substituting 2 into the expression above.
Mathematically, that would be 8(2) -7 = 16-7 = 9
