Question

12 what is the output of this function when the input is 4? output value =

Explanation:

Step1: Locate x=4 on x - axis

Find the position of \( x = 4 \) on the horizontal (x - axis) of the graph.

Step2: Find corresponding y - value

From the point \( x = 4 \) on the x - axis, move vertically (up or down) to intersect the graph. Then, find the corresponding value on the y - axis. By observing the graph, when \( x = 4 \), the \( y \) - value (output) is - 5.

Answer:

-5
