explaining graphs of functions\nexplain 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) until it intersects the graph of (y = f(x)). The y - coordinate of the intersection point is (f(3)).
Answer:
The y - coordinate of the point where the vertical line (x = 3) intersects the graph of (y=f(x)) is (f(3)).
