If an inverting amplifying circuit has a gain of 10 and ±15V power supplies are used. The values of input for which opamp would be in the linear region? Correct Answer ±1.5V

Gain= Rf/Rs= 10 and vo= (-Rf/Rs)*vs. → vo= -10vs and given -12V≤ vo ≤ 12V. → -15= -10vs. So, vs= 1.5V → 15=-10vs. So, vs=-1.5V.
