To determine which statement is true, let's analyze the $y$-intercepts of both functions:

1. Function A (from the graph):

   • The green line in the graph intercepts the $y$-axis at $y = 0$.

2. Function B (given as $y = 2x - 1$):

   • The equation $y = 2x - 1$ has a $y$-intercept of $-1$, as seen from the constant term $-1$ when $x = 0$.

Comparison of y-intercepts:

• The $y$-intercept of Function A is $0$.
• The $y$-intercept of Function B is $-1$.

Since $0 > -1$, the y-intercept of Function A is greater than the y-intercept of Function B.

Answer:

Statement 1 is true: The y-intercept of function A is greater than the y-intercept of function B.
