Answer 1

To classify the function \( f(x) = \frac{3x + 4}{8} \), we first simplify it.

The function can be rewritten as:

\[ f(x) = \frac{3x}{8} + \frac{4}{8} = \frac{3}{8}x + \frac{1}{2} \]

This is in the form \( f(x) = mx + b \), where:

• \( m = \frac{3}{8} \) (the slope)
• \( b = \frac{1}{2} \) (the y-intercept)

Since this is a linear equation, we classify the function as linear.

So the correct response is:

linear
