15. f(n)= 2n-3
a) =2(11)-7
=22-7
=15

=2(-6)-7
=-12-7
=-19

b) f(g)=-5x+1
= -5(41)+1
= -205+1
= -204

= -5(-16)+1
= 80+1
= 81

Multiply both 1/6=11/66, 3/11=9/66. 1/6 is bigger.

Answer: x=2π/3 and x=4π/3

Step-by-step explanation:

The equation we have is $\sqrt{3-2cosx} =2$ . All we have to do is get cosine alone to find the 2 values of x.

$3-2cosx=4\\-2cosx=1\\cosx=-\frac{1}{2}$

Now that we have our cosine left, we can use our unit circle to figure out when does cosx=-1/2. Cosine is the x value of the coordinate.

x=2π/3

x=4π/3
