Answer:
Step-by-step explanation:
Step1: find the interval of roots. Consider -3 and -2


Hence, the root must be on [-3,-2]
Step2: consider the middle point -2.5

Then, the root must be on [-3, -2.5]
Step 3: Repeat step 2 by finding the value of f at the middle point -2.75

Step 3: Repeat step 2 by finding the value of f at the middle point of the interval [-2.75,-2.5] which is -2.625

Step4: Repeat step 2 on [-2.75, -2.625]
Repeat step 2 until you got the root which is -2.701
