^{2}

Not sure what to do. If this was f(x) = 5x

^{2}I'd do (0,0) as the vertex and make a table to figure out some other points. But I'm really stuck with this super odd fraction. A video told me to use a number that, when squared, is divisible by the fractions denominator. 19 squared is 361! I can't even graph that on my homework. I've also tried using a table and some fractions, but the rise/run fraction works when you don't have an x value already. I'm just really stuck here.

2. f(x) = 2(x-11)

^{2}

I know that the vertex is (11, 0).

**How do I calculate the y value?**

Graphing f(x) = a(x-h)^2 is super hard for me. I've looked everywhere online and no one explains it. When I try solving it by using FOIL to turn it into general form, it's wrong. So obviously there's a way to solve these that isn't using general form.
