Answer

Explanation:

Step1: Determine the domain

The domain of a function is the set of all possible (x)-values. Looking at the graph, since it continues its trend beyond the displayed grid and there are no restrictions on (x) (it extends infinitely to the left and right), the domain is ((-\infty,\infty)). But wait, maybe there was a mis - look. If we assume the user's initial wrong input for domain was a mistake. Re - examining the graph (assuming standard coordinate grid interpretation), for a function that is a "V - like" shape (a piece - wise linear function). The left - most point's (x) - value is not restricted. So the domain is ((-\infty,\infty))

Step2: Determine the range

The range is the set of all possible (y) - values. The function has a maximum value (the vertex of the "V" - shaped graph). Let's find the vertex. The function is composed of two linear parts. The left - hand line has a slope (m_1 = 1) (from ((-4,0)) to ((0, - 4))) and the right - hand line has a slope (m_2=-1) (from ((0,-4)) to ((4, - 8))). The vertex of the function (the highest point of the "V" - shape) occurs at (y = - 4) (the (y) - coordinate of the point ((0,-4))) and it extends downwards infinitely. So the range is ((-\infty,-4])

Step3: Find (x) - intercepts

The (x) - intercepts are the points where (y = 0). Looking at the graph, when (y = 0), (x=-4). So the (x) - intercept is (-4)

Step4: Find (y) - intercept

The (y) - intercept is the point where (x = 0). From the graph, when (x = 0), (y=-4)

Step5: Find (f(-4)) and (f(1))

For (f(-4)): When (x=-4), from the graph (y = 0), so (f(-4)=0) For (f(1)): The right - hand part of the function (for (x\geq0)) has the equation (y=-x - 4) (using the slope - intercept form (y=mx + b) with (m=-1) and (b = - 4)). Substitute (x = 1) into (y=-x - 4), we get (y=-1-4=-5)

Answer:

a. Domain: ((-\infty,\infty)) b. Range: ((-\infty,-4]) c. A. The (x) - intercept(s) is(are) (-4) d. A. The (y) - intercept is (-4) e. (f(-4)=0), (f(1)=-5)
