The relationship between two variables v and x is known to be: The following data points are given: 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 15 25 32 33 373538 39442 Determine the constants a and b by curve-fitting the equation to the data points. Make a plot of y versus x. In the plot show the data points with markers and the curve-fitted equation with a solid line. Use the equation to estimate y at x-23. (The curve fitting can be done by writing the reciprocal of the equation and using a first-order polynomial.)
