Question

Find the output, y, when the input, 2, is -9. Y = Y < 8+ 4 1 -8 2 4 6 -6+

Answer 1

when x = -9, y = 1

Here, we want to get the value of y when x = -9

To find this, we look at the point x= -9 on the x-axis

After getting this, we trace it to the graph

Looking at the graph, the graph crosses the x-axis at exactly this point

What this mean is that the value of y at that point is 1

Hence, for input -9, output is 1
