operational amplifier - Level shifting pedal output to 0-5V


I have an accelerator pedal which outputs .75 to 4 V and I need to convert this to a 0-5 V output for my controller.I found a circuit that fits(shown below),which uses an opamp in non-inverting configuration with feedback,but I'm not sure how it works so I am not able to adjust the resistor values on my own to get the desired output.Can someone explain how I should calculate the resistor values?
