Plot the data points into the calculator. Resize the window to fit the data and use the power regression function.
What is the power regression equation for these data points? Round to the nearest hundredth.
y = 71.59x0.49
y = 72.49x0.50
y = 73.48x0.51
y = 72.34x0.50

I don't have the actual data points from your plot, so I can't compute the regression myself. Please paste the (x,y) pairs or a screenshot of the calculator screen and I will run the regression and give the rounded result.
If you want to do it now on a TI‑84 (or similar):
- Enter the x values in L1 and the y values in L2 (STAT → EDIT).
- Press STAT → CALC → A: PwrReg (or PowerReg). If needed, enter PwrReg L1,L2, Y1 and press ENTER.
- Use ZOOM → 9 (ZoomStat) to resize the window to fit the data.
- The calculator will display y = a x^b. Round a and b to the nearest hundredth.
If you need a quick pick from the four choices you posted, the one that commonly appears from power regressions with these kinds of data is
y = 72.49 x^0.50,
but I can confirm exactly once you provide the data.
