Which graph represents a function?

Top Left

Step-by-step explanation:

This graph is the only graph that passes the vertical line test.

If you were to draw a vertical line through the graph, it should only intersect at  one point, which all the other graphs fail.

Hope this helped!

It is the first one ma'm.

∠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°
