This is grade 11 algebra.

The task is: Image #192480 - CtrlV.in Image Hosting (pasted image), or in writing: Draw each of the graphs on the Cartesian plane below. Clearly show the symmetry axis, the coordinates of the turning point and the y-intercept on these graphs.

f(x) = 2x^2

g(x) = 2(x-2)^2

h(x) - 2x^2-2

k(x) = 2(x+2)^2

m(x) = 2x^2+2

Then, "explain in words what happened to f to form g, h, k, and m".

I'm not too sure about either section, but I can probably figure out the first part. If I'm not mistaken, it's just u-shaped parabolas. I have no idea what the written explanation should be though. My teacher isn't much use so any help will be appreciated.
