The function of f(x) is to be graphed on a coordinate plane f(x) {-x x< 0 1. x> 0}

The graph is attached

Step-by-step explanation:

Here the given function is

Now consider

y = -x

The graph is a line at 45° to the negative x axis.

But as x <0, so it shall be a line only in the second quadrant.

Also for f(x) = 1

It a horizontal line passing through y axis at 1.

But as x > 0, So we have the line only to the right of y axis.

The graph is attached.
