2. Use the graph of y=-x2 - 2x + 3 to solve
the equation –X2 - 2x + 3-0. What are
the solutions?
A 4
B -1 and 4
C 1 and -3

1 and -3

Step-by-step explanation:

The values of the graph is where the graph intersect at the line x

Which is 1 and -3

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

45
