Question

Help?? Will fan and give medal for correct answer!!!! question attached below

Answer 1

$$
g(x)=kx^2\\
g(10)=k10^2=50\\
k=\cfrac{50}{100}=\cfrac{1}{2}\\
g(x)=\cfrac{x^2}{2}\\
g(2)=2\\
g(3)=4.5
$$
There's only one chart that matches these figures.

Answer 2

Which one? the equation is written really small on my phone i can hardly see @ybarrap

Answer 3

How's this?
$$
\Huge{
g(x)=kx^2\\
g(10)=k10^2=50\\
k=\cfrac{50}{100}=\cfrac{1}{2}\\
g(x)=\cfrac{x^2}{2}\\
g(2)=2\\
g(3)=4.5
}
$$

Answer 4

Oh thats better! @ybarrap
