    i understand where the -4 comes from, but the x^2 is confusing me.

    x^2 is original graph of the quadratic equation (parent function )

    |dw:1439741221254:dw| like this so they are saying -4 is shifting from the original graph(0)

    vertex form y=a(x-h)^2+k k= vertical shift h= horizontal shift

    using vertex form, you can always plug in numbers to check.

    if k is positive you should shift the f(x) some units above the x-axis if k is negative shift below the x-axis some units for horizontal you would be careful abt signs if h is negative shift the function some units to the Right side if h is positive shift the function some units to the left side

    \[y=a(x-(-4))^2+k\] when negative by negative 4 :)
