Question

Solve the problem using your graphing calculator. Round all parameter values to the nearest hundredth. The following table compares the hours ten college students spent studying for an exam resulting scores on the exam. Choose the function that best represents the data.

Answer 1

The correct answer is option ii.
`\( f(x) = 3.73 + 34.59x \)`.

To determine the best-fitting function for the given data, we can use the provided hours studying and exam scores to compare the options.

The general form of the linear function is
`\(f(x) = mx + b\)`, where
`\(m\)` is the slope and \(b\) is the y-intercept. We need to find the values of
`\(m\)` and
`\(b\)`that best fit the data.

Using the data provided, we can perform linear regression or use a graphing calculator to find the values of
`\(m\)` and
`\(b\)`. After calculations, the correct function that best represents the data is:

`\[ f(x) = 3.73 + 34.59x \]`

Therefore, the correct option is:

`ii. \( f(x) = 3.73 + 34.59x \)`
