To find the output of the function \( y = 3x + 6 \) when \( x = 0.3 \), we can substitute \( x \) with \( 0.3 \):

\[ y = 3(0.3) + 6 \]

Calculating this step-by-step:

  1. Multiply \( 3 \) by \( 0.3 \):

    \[ 3 \times 0.3 = 0.9 \]

  2. Then add \( 6 \):

    \[ 0.9 + 6 = 6.9 \]

So, when \( x = 0.3 \), the output \( y \) is \( 6.9 \).

The correct response is:

6.9
