Answer:
b.(-2, -1), (3, 4)
Step-by-step explanation:
We are given function as
We can verify each intervals
At (-6,-5):
Firstly we will plug x=-6
now, we can plug x=-5
since, both are positive values
So, zeros can not lie between them
At (-4,-3):
Firstly we will plug x=-4
now, we can plug x=-3
since, both are positive values
So, zeros can not lie between them
At (-2,-1):
Firstly we will plug x=-2
now, we can plug x=-1
since, one is positive and another is negative
So, zeros will lie between them
At (3,4):
Firstly we will plug x=3
now, we can plug x=4
since, one is positive and another is negative
So, zeros will lie between them
zeros will be between
(-2, -1), (3, 4)
