Write the function in the form y = f(u) and u = g(x). Then find dy/dx as a function of x.y = 
9
A. y = u9; u = 6x2 - 
- x; 
= 9
8
B. y = u9; u = 6x2 - 
- x; 
= 9
8
C. y = u9; u = 6x2 - 
- x; 
= 9
8
D. y = 6u2 - 
- u; u = x9; 
= 12x18 - 
- x9
6a(2a2 + 4a + 2) - 3a(2a2 - 7a + 8) =
a. 6a3 + 45a2 - 12a b. 12a3 + 3a2 - 36a c. 18a3 + 45a2 - 36a d. 18a2 + 3a2 + 12a e. 6a3 + 3a2 - 12a
Find the functions f and g so that F(x) = (f o g) (x).F(x) = ?5x + 5?
A. f(x) = ?x?, g(x) = 5x + 5 B. f(x) = ?-x?, g(x) = 5x - 5 C. f(x) = x, g(x) = 5x + 5 D. f(x) = -?x?, g(x) = 5x + 5
