Problem
$f(x)=\sqrt{10 x+5}$ \[ \begin{array}{l} f(x)=\sqrt{10 x+5} \\ f(3)=? \end{array} \] Round your answer to two decimal places.
Solution
Step 1 ：Given the function \(f(x)=\sqrt{10 x+5}\), we need to find the value of \(f(3)\).
Step 2 ：Substitute \(x = 3\) into the function: \(f(3)=\sqrt{10*3+5}\).
Step 3 ：Calculate the value to get \(f(3) = 5.92\).
Step 4 ：Final Answer: \(f(3) = \boxed{5.92}\)
