Solution
Solution Steps
To find the linear function \( f(x) \) that corresponds to the given table of values, we need to determine the slope and the y-intercept of the line. The slope \( m \) can be calculated using the formula \( m = \frac{f(x_2) - f(x_1)}{x_2 - x_1} \). Once the slope is determined, we can use one of the points to solve for the y-intercept \( b \) using the equation \( f(x) = mx + b \).
Step 1: Calculate the Slope
To find the slope \( m \) of the linear function, we use the formula:
\[
m = \frac{f(x_2) - f(x_1)}{x_2 - x_1}
\]
Using the points \( (0, 1) \) and \( (1, 18) \):
\[
m = \frac{18 - 1}{1 - 0} = 17.0
\]
Step 2: Calculate the Y-Intercept
Next, we calculate the y-intercept \( b \) using the point-slope form of the linear equation:
\[
f(x) = mx + b
\]
Substituting \( m = 17.0 \) and using the point \( (0, 1) \):
\[
1 = 17.0 \cdot 0 + b \implies b = 1.0
\]
Step 3: Write the Linear Function
Now that we have both \( m \) and \( b \), we can express the linear function:
\[
f(x) = 17.0x + 1.0
\]
Final Answer
The linear function corresponding to the table of values is
\[
\boxed{f(x) = 17.0x + 1.0}
\]
