Sketch a graph of x2 + y2 = 100. Homework Help ✎
Is it a function?
What are its domain and range?
Draw a central angle that measures
radians. If you remove this wedge of the circle, how much area remains?
Does each x-value on the graph of the function have only one corresponding y-value?
Domain: −10 ≤ x ≤ 10
Range: −10 ≤ y ≤ 10
See the unit circle graph at right.
What portion of the circle is shaded?
