Consider the inverting amplifier shown in Figure 9.8. Assume the op-amp is ideal. Determine the resistor values \(R_{1}\) and \(R_{2}\) to produce a closed-loop voltage gain of

(a) -3.0 ,

(b) -8.0 ,

(c) -20 , and

(d) -0.50 . In each case the largest resistor is to be limited to \(200 \mathrm{k} \Omega\).
