The answer is c
Because x doesn’t repeat

Answer:

Step-by-step explanation:

you know what output you get from the input.

For example, you know that if you put in -5, you get -2, or if you put in 4, you get -2.

Even though there are two inputs for one output, it is still a function.

------------------------------------------------------------------------

If there are two outputs for one input, it is not a function.

For example, on d, when -5 is an input, you don't know if you're going to get 3 or 7. So, it's not a function.

Find the quadratic regression for (-1,1) , (0,0) , (1,1)

Answers

3 points define a parabola, so the regression will be unique. You want to find a quadratic polynomial $P_2(x)=\beta_0+\beta_1x+\beta_2x^2$ such that

$\begin{cases}\beta_0-\beta_1+\beta_2=1\n\beta_0=0\n\beta_0+\beta_1+\beta_2=1\end{cases}$

where the system above is generated by setting $P_2(-1)=1$ , $P_2(0)=0$ , and $P_2(1)=1$ .

Since $\beta_0=0$ , we have

$\begin{cases}-\beta_1+\beta_2=1\n\beta_1+\beta_2=1\end{cases}\implies2\beta_2=2\implies\beta_2=1\implies\beta_1=0$

So the regression for the given data points is $P_2(x)=x^2$ .
