I don't know if that is

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

or

f(x) = x^2 ...

Since you needed an equation, I will assume that the - sign was supposed to be an = sign

If not, make the necessary changes, by factoring out the -1

y = x^2 + 14x - 50

= x^2 + 14x +**49 - 49** - 50

= (x+7)^2 - 1

I will leave the graphing to you.
