use the graph at right to find the given function value by locating the input on the horizontal axis, moving directly up or down to the graph of the function, and then moving left or right to find the output on the vertical axis. find f(4).\nf(4)=□\n(type an integer or a decimal.)
Answer
Explanation:
Step1: Locate x = 4 on x - axis
Find the value 4 on the horizontal x - axis.
Step2: Move up to the graph
Move vertically up from x = 4 until reaching the graph of the function.
Step3: Find y - value
Move horizontally to the y - axis to determine the corresponding y - value. From the graph, when x = 4, y = 0.
