find the value of f(-7). y = f(x)
find the value of f(-7). y = f(x)
Answer
Explanation:
Step1: Locate x = -7 on x - axis
Find -7 on the x - axis.
Step2: Determine corresponding y - value
Move vertically from x = -7 until intersecting the graph of y = f(x). The y - value at the intersection is the value of f(-7). From the graph, when x=-7, y = - 4.
Answer:
-4
