I have a test tomorrow and I really don't get this, please help me.
"Use transformations and the zeros of the quadratic function f(x)=(x6)(x+4) to determine the zeros of each of the following functions
a) y=2f(x) b) y=f(2x) c) y=f(0.5x)"
I am so lost, I don't get what it means by 'the zeros', please, please, please help me!

I really don't understand this, I don't mean to be a pain, but I really need to understand this.
