Fitting quadratic and exponential functions to scatter plots

Google Classroom

Problem

Below are 4 scatter plots showing the same data for the quantities f and x. Each plot uses a different unit for the vertical and horizontal axes.
Judging from these scatter plots, which type of function would be the best fit for f, left parenthesis, x, right parenthesis?
Choose 1 answer:
A scatter plot on an coordinate plane where the horizontal axis is x and the vertical axis is f. The points start around the origin and curve up as x increases.
A scatter plot on an coordinate plane where the horizontal axis is square root of x and the vertical axis is f. The points start around the origin and curve up as x increases.
A scatter plot on an coordinate plane where the horizontal axis is x squared and the vertical axis is f. The points start around the origin and curve up as x increases.
A scatter plot on an coordinate plane where the horizontal axis is x and the vertical axis is log of f. The points start around the origin of the and increase diagonally as x increases.
