Answer:
The given function is
f(x)=cos 3x-7 x²+ 4x
f'(x)=-3 sin 3 x-14 x+4
When you will draw the graph of the function , you will find that root of the function lie between (-1,0).
Consider initial root as,
Using Newton method to find the roots of the equation
So, root of the equation is
=0.1688878
=0.1689(approx)
Answer:
B
Step-by-step explanation:
Let y be the function f(x)
for inverse
x =y÷3-2
or, x + 2 = y ÷3
or, ( x + 2)3 =y
so inverse of f(x) is (x + 2) 3
8.394-2.199= 6.195 but rounded to the nearest hundred is 6.2
