1 answer

To determine which linear function has the greater initial value, we first need to identify the initial values of both functions.

Linear Function 1:
Taesha's savings can be represented as:
\[ y = 25x + 50 \]
Here, the initial value (y-intercept) is \( 50 \) (when \( x = 0 \)).

Linear Function 2:
Joshua's savings is given by the equation:
\[ y = 37x + 40 \]
In this case, the initial value (y-intercept) is \( 40 \) (when \( x = 0 \)).

Comparison of Initial Values:

  • Initial value of Linear Function 1 (Taesha): \( 50 \)
  • Initial value of Linear Function 2 (Joshua): \( 40 \)

Since \( 50 > 40 \), we conclude that Linear Function 1 has the greater initial value.

Therefore, the answer is: 1
