Answer:
The correct option is d
The correct option is d
The correct option is c
the correct option is b
Step-by-step explanation:
The given equation is
The give interval is
Now differentiating the equation
Therefore the equation is positive at the given interval
Now at x= 1
Now at x= 2
Now at the interval (1,2)
i.e
this tell us that there is a value z within 1,2 and
f(z) = 0
Which implies that there is a root within (1,2) according to the intermediate value theorem
