Question

which is the graph of the function $f(x) = \sqrt{\frac{9}{4}x}$?

Explanation:

Answer:

The provided graph (the one starting at the origin, increasing with a decreasing slope, passing through points like (4, 3) since $f(4)=\sqrt{\frac{9}{4}\times4}=3$) is the graph of $f(x)=\sqrt{\frac{9}{4}x}$.
