If you have f(-2), you are expected to sub in -2 for x to find out the y value at that x value. Find -2 on the graph and see what y is at that point. y is 2, therefore, f(-2) = 2.

If tap and bre are supplementary and bre is its own complement, find the measure of tap. explain how you arrived at your answer
Pie
Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
                           m∠bre + m∠bre = 90°
                                   m∠bre = 45°

Then, for the relationship of bre and tap, we have the equation,
                       m∠bre + m∠tap = 180°
                        45° + m∠tap = 180°
                                m∠tap = 135°

The measure of tap is equal to 135°.
