polynomial equation
I am setting up a calibration curve, where x= concentration and y=
absorbance. The curve is polynomial. after plotting x and y values using a scattergraph and applying a trend line, i got the following regression line: y= -0.0881x^2+2.8089x+0.0505. If the absorbance reading (y) = 0.212, how do I calculate the value of x? Thanks in advance |
