To find the initial value \( b \) of the linear function, we can use the formula for a linear function in slope-intercept form, which is:

\[ y = mx + b \]

where \( m \) is the slope (rate of change) and \( b \) is the y-intercept (initial value).

Given:

  • The rate of change \( m = -47 \)
  • The point \( (x, y) = (14, 3) \)

We can substitute the values into the equation:

\[ 3 = -47(14) + b \]

Calculating \( -47(14) \):

\[ -47 \times 14 = -658 \]

Now substituting back in:

\[ 3 = -658 + b \]

To solve for \( b \), add \( 658 \) to both sides:

\[ b = 3 + 658 \]

\[ b = 661 \]

None of the provided responses match this result, indicating that there may have been a misunderstanding or mistake in the provided options.

The correct calculation determines that the initial value \( b \) is \( 661 \). If you meant to look for a closer set of calculations or assumptions, please clarify!
