Hello, I need a little help here. I thought I understood this stuff but can't figure out this one concept. We're dealing with functions so here goes

f(x)=3x^2+2x-4
Find the value of f(x+1)

I thought it would work like this:
f(x+1)=3(x+1)^2+2(x+1)-4
=3(x^2+1)+2x+2-4
=3x^2+3+2x-2
=3x^2+2x+1

The answer is actually f(x+1)= 3x^2+8x+1

Can someone please explain this to me and tell me what i'm doing wrong?

I was trying to describe this to a friend of mine, but I can't think of any simpler way to put it... the best I got is
"Is a spherical object is the only closed three-dimensional space with no holes?" But that doesn't really capture it because you could say "well... what about a cube?"

Simplifying questions... gotta love it :)

Assume the viewer is at sea level, there are no mountains or other obstructions.
The plane is travelling at 39,000 ft
The ground distance should be based upon when the plane appears on the west horizon and when it disappears on the east horizon.
It should be assumed the track of the plane is perfectly west/east over the viewer.
