Question

what is the value of the following function when x = 0?
options: y = -5; y = -2; y = -1

Explanation:

Step1: Locate x=0 on x-axis

Find the vertical line where x = 0 (the y - axis) on the graph.

Step2: Find intersection with the function

Look at the point where the graph of the function intersects the line x = 0. From the graph, when x = 0, the y - value (the value of the function at x = 0) is - 2.

Answer:

y = - 2 (corresponding to the option: y = - 2)
