Step-by-step explanation:
the second and the 6th options keep the same graph but shift it to the left.
the other options :
the first option changes the graph (the factor -2 stretched and flips the graph).
the third and the 5th options shift the graph up and down. but not to the left.
the 4th option shifts it to the right.
when you add a constant inside the x terms, you shift to the left.
when you subtract a constant inside the x terms, you shift to the right.
e.g. when having f(x+2), then everything, that should happen at x+2 happens already at x. 2 units earlier, and therefore a shift to the left.
in the other direction, f(x-2) makes everything that should have happened at x-2 happen finally at x. so, everything shifts 2 units to the right.

Answer:
9.45 (rounded)
Step-by-step explanation:
- The formula is to divide the centimeters by 2.54, and this will give you the amount of inches.
There are several information's of immense importance already given in the question. Let us write them down first
Number of edges of the regular polyhedron (E) = 30
Number of vertices of the regular polyhedron (V) = 12
Let us assume the number of faces of the regular polyhedron = F
Then
V - E + F = 2
12 - 30 + F = 2
f - 18 = 2
F = 20
From the above deduction, it can be easily concluded that the number of faces of the regular polyhedron is 20.
