Given the scatter plot, choose the function that best fits the data.

scatter plot with data points that form an upward curve staring at the origin and continuing to the right

f(x) = 2x

f(x) = 2x

f(x) = −2x

f(x) = 2x2

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.
