Part (9)</u></h3>
The values of x for which g(x) < f(x) are the values of x between the points of intersection of the two functions: points D and A.
From part (2) of the question, we found that A = (3, 0).
From part (5) of the question, we found that D = (-4, 7).
Therefore, the values of x for which g(x) < f(x) are -4 < x < 3.
In interval notation this is: (-4, 3).

Answer:</h3><h3>
-3.5,-0.5</h3>
Step-by-step explanation:

Recall the half-angle identity:

So in order to find

, we only need to know the value of

. But there are two possible values. To decide which to take, we use the given information: we know that

lies in quadrant III, which means

, so

, which places

in quadrant II. In this quadrant, the sine of angle is positive, and so


is an angle of a ray whose terminal point,

lies on the circle

. The

-coordinate is all we need to know in order to find that

. So,
1.C
2.B
3.C
4.C OR B (though im still not 100% sure on this one but i think its B)
5.B
