    I am very confused: Why do you have a second equals sign in the middle of the function, and where is h?

    what? I'm confused too. The way you typed your problem is that exactly the way it looks?

    \[f(x)=\frac{1}{2}(x \pm 5)^2-9\] i think it should either be + or -

    \[f(x)=\frac{1}{2}(x=5)^2-9...\]I can't seem to make any sense of this.

    \[f(x)=\frac{1}{2}(x+5)^2-9\] \[f(x)=a(x-h)^2+k\] what is h?

    well we want -h=5 right?

    so if -h=5, then h=?
