the graph of a function f is shown below. find f(-1).
the graph of a function f is shown below. find f(-1).
Answer
Explanation:
Step1: Locate x = -1 on x - axis
Find x = -1 on the horizontal axis.
Step2: Determine corresponding y - value
Move vertically from x = -1 until intersecting the graph of the function. Then move horizontally to find the y - value. The graph of the function intersects the vertical line x=-1 at the point (-1, - 2). So the y - value corresponding to x = -1 is -2.
Answer:
-2
