is there more to the question?

OpenStudy (anonymous):

The function is linear on two intervals. It is not strictly linear, however.

What is the absolute value of -4?

OpenStudy (anonymous):

And 4 + 10?

OpenStudy (anonymous):

No, 4 added to 10. Not multiplied.

OpenStudy (anonymous):

Right, so f(-4) = 14

OpenStudy (anonymous):

Not strictly. It's linear on x>= 0 and x <= 0. In both interval the slopes are perpendicular to each other.

OpenStudy (anonymous):

No. If the question is simply "is it linear?", then the answer is no.
