any reflection on a convex mirror is always going to be upright right?
is any reflection on a concave mirror always inverted?

Perfect! Thank you. You are awesome.

In convex (diverging mirrors) you will always have "SUV"'s
The image is Smaller, Upright, and Virtual

In concave (converging mirrors) you have 5 possible situations...
1) The object is outside the radius of the mirror (remember radius = 2 times the focal length)
In this case the image is real, inverted, and smaller
2)The object is at the radius of the mirror
In this case the image is real, inverted, and the same size
3) The object is inside the radius of the mirror, but outside the focal length
In this case the image is real, inverted, and larger
4) The object is at the focal length
In this case the image doesn't form
5) The object is inside the focal length
In this case the image is virtual, upright, and larger

To memorize them, just remember convex mirrors are divergent and are always SUV's, and with concave convergent mirrors work your way in from outside the radius, the image gets larger and larger.

Also, concave and convex "LENSES" (vs mirrors) are exactly the opposite. A concave lens is diverging and a convex lens is converging, and they have the opposite effects.

Optics blows.

Never knew a flat out rule for the magnification bit. That's helpful!

Agree with all of this. DO NOT get confused when they give you concave vs. convex.

If it's converging - it's a convex lens or a concave mirror
Diverging - concave lens or convex mirror.

Notice that they are flipped.
