The shown circuit is

• an inverting amplifier

• a non-inverting amplifier

• a unity-gain amplifier

• non of the choices

The circuit shown is

• an integrator

• a differentiator

• a non-inverting amplifier

• an inverting amplifier

The gain of a non-inverting amplifier is

• positive

• negative

• larger than 1

• smaller than 1
