I don't know if you still need help. but the answer is the first one.
Answer:
x=1/3
Step-by-step explanation:
A function f is given as
in the interval [0,1]
This function f being an algebraic polynomial is continuous in the interval [0,1] and also f is differntiable in the open interval (0,1)
Hence mean value theorem applies for f in the given interval

The value

Find derivative for f

Equate this to -5 to check mean value theorem

We find that 1/3 lies inside the interval (0,1)
They are all perfect squares
(9x+2)(9x+20
(9x+2)^2
1. a. 0=0, 4x=4x, -18=-18
b. 3
2.a. 0=-2, 2= 0
