if f(x)=3/x+2-square root x-2, complete the following statement (round your answer to the nearest hundredth): f(7)=___

$f(x)=\frac{3}{x}+2-\sqrt{x}-2$

$f(7)=\frac{3}{7}-\sqrt7\approx-2.22$

f(x)=3/x+2-square root x-2

Do you mean ....

$f(x)=\frac{3}{x}+2-\sqrt x-2\\ or\\ f(x)=\frac{3}{x+2}-\sqrt {x-2}\\ $

Or something else altogether
