Question

help pleaseeee

Answer 1

The vertical translation is obviously -2.
We need to find what the stretch is.
Take a point in f(x) as an example.
For example, what is f(1) = ?

Answer 2

@divagirl421 Are you there?

Answer 3

We have f(0)=-2 and f(2)=0.
For A we have
\[f(2)=-(-2)^2-2=-6\ne0\]
For B we have :
\[f(2)=6(2)^2-2=22\ne0\]
For D we have :7
\[f(2)=2^2-2=2\ne0\]
But for C we have :
\[f(2)=0.5\times2^2-2=2-2=0\]
So :
The function is
\[f(x)=0.5x^2-2\]

Answer 4

thats wrong

Answer 5

It's \(f(x) = 0.6x^2 - 2\)

Answer 6

@Noura11 f(2) is not equal to 0 (it's just close to zero).
