Step 1 :Let's find the derivative of the function \(f(x)=\sqrt{x+1}\).
Step 2 :The derivative of \(f(x)=\sqrt{x+1}\) is \(f'(x)=\frac{1}{2\sqrt{x+1}}\).
Step 3 :Substitute \(x=0\) into the derivative to find the slope of the tangent line at \(x=0\).
Step 4 :The slope of the tangent line to the function \(f(x)=\sqrt{x+1}\) at \(x=0\) is \(\boxed{\frac{1}{2}}\).
