Given:

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

Let's find g(x).

From the given graph, we can see the graph of g(x) is compressed horizontally from f(x).

Thus, to find g(x) aply the transformation rules for function.

We have:

Horizontal compression of b units ==> f(bx)

Given the point on g(x):

(x, y) ==> (2, 12)

Let's solve for the value of the compressed factor.

We have:

[tex]\begin{gathered} 12=b(2)^2 \\ \\ 12=b4 \\ \\ \text{Divide both sides by 4:} \\ \frac{12}{4}=\frac{b4}{4} \\ \\ 3=b \\ \\ b=3 \end{gathered}[/tex]

This means the graph of f(x) was compressed horizontally by a factor of 3 to get g(x).

Thus, to write the function for g(x), we have:

[tex]g(x)=3x^2[/tex]

ANSWER:

[tex]D\text{.}g(x)=3x^2[/tex]
