Let $f(x)=3+\frac{1}{x}$.

(a) Find the arithmetic average of the values $f({\frac{6}{5}}),f({\frac{7}{5}}),f({\frac{8}{5}}),f({\frac{9}{5}}),$ and $f(2)$.

$f_{\mathrm{ave}}$ $=$

(b) Find the arithmetic average of the values $f(1.1),f(1.2),f(1.3),f(1.4),...,f(2)$.

$f_{\mathrm{ave}}$ $=$

(c) Find the average of the values $f$ on $(1,2)$.

$f_{\mathrm{ave}}$ $=$
