Question

What is the output y, when the input x is -1

Answer 1

The output value is 3 when the input is -1

Here, we want to get the output value for x = -1

To get the output value, we have to take a look at the graph

We need the value of y when x = -1

Looking at the graph, we have this as

y = 3

We only need to get the point at which x = -1, trace it to the function, then find the y-value corresponding
