I am simulating the use of a tl074 quad op-amp and i have configured one of the op-amps as a non-inverting op-amp, where R1=1 Meg and R2=4 Meg and the supply voltage is 9V. Every time i put a signal in, the output is always offset negatively. Is this how the op-amp is supposed to work? or are there more components to add to get just an amplified signal rather than a negatively offset amplified signal? This is basically the configuration i used below.
