write the quadratic function f(x)x^2+14x50 in the form f(x)=a(xh)^2+k by completing the square and graph

Reiny,
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.
