How to Find Values of Functions from Graphs?
First, draw a vertical line through \(4\) on the \(x\)-axis. Then mark the intersection of the vertical line \(x = 4\) and the graph \(f (x)\). Now draw a horizontal line from the point of intersection to the \(y\)-axis. So, the value of the function \(f(x)\) at \(x = 4\) is \(7\). Exercises for Finding […]
