F(x) = x^2 + 3 g(x) = 4x - 3 Find (f°g)(-1)

a. 4
b. -52
c. -4
d. 52

Step-by-step explanation:

g(-1) = 4(-1) - 3 = -4 -3 = -7

f(-7) = (-7)^2 + 3 = 49 + 3 = 52

Answer is D

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
