Simplify completely by removing all parentheses. Given the functions f(x) = x2 + 2 and g(x) = 2x – 5, calculate the following:
g(f(x)) = ?

g(x^2+2)=2x^2-1

i dont really.know

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
