0.3

Answer 1

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

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

Calculating it step by step:

1. Multiply \( 3 \) by \( 0.3 \): \[ 3 \times 0.3 = 0.9 \]

2. Add \( 6 \): \[ 0.9 + 6 = 6.9 \]

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

The correct response is 6.9.
