By imagining tangent lines at points P,, P,, and P2, state whether the slopes are positive, zero, or negative at these points. P2 Pa slope at P O The slope is positive at P . O The slope is zero at P . O The slope is negative at P. slope at P, O The slope is positive at P2. O The slope is zero at P2. O The slope is negative at P2. slope at P3 O The slope is positive at P3. O The slope is zero at P. O The slope is negative at P3
