The Deep Dive
The function \( f(x) \) is defined for all \( x \) where \( -4 \leq x < 1 \) and \( x > 1 \). This means the domain covers all real numbers from -4 to infinity, represented as \( [-4, \infty) \). To find the intercepts, we check where the function crosses the axes. For the x-intercept, set \( f(x) = 0 \) and solve: 1. In the segment \( x + 6 = 0 \) leads to \( x = -6 \) but this is outside the domain. 2. In the segment \( -x + 3 = 0 \) leads to \( x = 3 \), which is in the domain, giving the x-intercept at (3, 0). The y-intercept is found with \( f(0) = 0 + 6 = 6 \), so it is at (0, 6). Therefore, the intercepts are at (3, 0) and (0, 6). So, A. The intercepts are (3, 0), (0, 6).
