Summer Preparation for PRECALCULUS HONORS This worksheet is a review of the entering objectives for Precalculus with Analysis and is due on the first day back to school. Please show work NEATLY and on a SEPARATE sheet of paper. Have a great summer!! We are looking forward to seeing you in August. _Your future Precalculus Honors Teachers In exercises 1-2, find the points that are symmetric to the given point (a) across the x-axis, (b) across the y-axis, and (c) across the origin 1.
