explaining graphs of functions explain how to use a graph of the function f(x) to find f(3).
Answer
Explanation:
Step1: Locate x - value on x - axis
Locate (x = 3) on the x - axis of the graph of (y=f(x)).
Step2: Find corresponding y - value
Draw a vertical line through (x = 3). The point where this vertical line intersects the graph of the function (y = f(x)) has coordinates ((3,y)). The y - coordinate of this intersection point is (f(3)).
Answer:
The y - coordinate of the point of intersection of the vertical line (x = 3) and the graph of (y=f(x)) is (f(3)).
