Please Help! It is Pre-Calc and I need to know the answer!

The limit of a continuous function at a point is just the value of that function at the point.

a. f(x)=10

f(-1)=10

f(x)=x

f(-1)=-1

a. 10 b=-1, choice a

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
