Answer:
-1
Step-by-step explanation:
From the graph, the y-coordinate of the circled point on the y-axis is the value of f(0). (The y-axis has equation x=0.) That coordinate is -1, so f(0) = -1.
__
From the equation, substituting x=0 makes all of the x-terms disappear, leaving only the constant.
f(0) = -0 +0 -1
f(0) = -1
