Homework Statement
How do I simplify the transformation of this equation?
y=-2[-1/3(x+2)]^2-4
Homework Equations
af(k(x-d))+c
The Attempt at a Solution
If this was a linear equation I would simply distribute the -1/3 into (x+2) and then distribute -2 into the (-1/3x -2/3) then collect -2/3 with the -4 right?
Which would leave me 2/3x-8/3
I tried this with the quadratic equation, which gives me 2/3x^2-8/3 but it can't be correct. I lose the reflection about the x so I know it's not right.
I've tried searching online but find the steps for simplifying this type of equation.
Thanks in advance
