Answer:
-3
Step-by-step explanation:
The graph shows the straight line.
To find the value at x = 2, draw the vertical line passing through the point (2,0). This line intersect the graph at some point. Draw the horizontal line through this point of intersection. This line intersects y-axis at point (0,-3). This means that the coordinates of the point lying on the graph are (2,-3) so
f(2) = -3
