Graphs of Functions

Everything in green is correct so far. But I'm stuck on (f) and I don't know what to do.

The question is asking:

For what values of 'x' - the value of f(x) is negative (or the graph is below the x-axis) ?

Solving an inequality means finding all values of the variable (x) for which it is true. The graph represents the equation y = f(x).

Look for all the places on the graph where y is equal to zero or less than zero. Then find the values of x at those points. What are they?

You don't appear to have been told what form the answer should take; it might be an inequality, or an interval, or a union of sets, for example. You'll have to determine that by entering your answer in some form, and seeing what the response is.

Thank you both for giving me all of the instructions. That's exactly what I was looking for since I didn't understand this type of math.
