Answer: B


Discussion: F(x), shown in red appears to be translated downward 3 units from G(x) and is a bit flatter (implying a scaling) from  G(x).  B is the likely  answer.  Note also that for the answer in B

F(4) =  .2 (4)^2 -3  = 3.2 which is consistent with the graphs shown.

Answer:

The equation of the resulting function F(x) is:

[tex]F(x)=0.2x^2-3[/tex]

Hence, option: B is correct.

Step-by-step explanation:

We are given a graph of the function G(x) as:

[tex]G(x)=x^2[/tex]

We are asked to find what could be the possible representation of the function F(x).

We know that the graph of function F(x) is a horizontal stretch of the function G(x).

This means that the factor that is multiplied to G(x) is 'k'

where 0< k <1.

Also the graph is shifted 3 units vertically down hence the graph of the resulting function F(x) is:

[tex]F(x)=0.2x^2-3[/tex]
