Thank you for the comment! The root is where the graph is crossing the x-axis. So, it will always lie in an interval where the graph is going from positive to negative or negative to positive, y coordinates. When f(x) is positive it replaces the positive value on the y-axis, so that we still have both positive and negative values in the interval. Therefore: The positive value between f(a) and f(b) changes when f(x) is positive. And the negative value between f(a) and f(b) changes when f(x) is negative. Hope this helps…
Thankyou For this Video, It was really informative and easy to understand and it really helped me to complete my assignment 😅
Thank you for the cheer…
And you are most welcome…
Why is it F(a) changing when f(x) is a positive? Shouldn't A change when f(x) is negative and B change when f(x) is positive?
Thank you for the comment!

can you do for the question i. im stil stuck how to solve when the interval was 0
thank you so much for this wonderfull video
You are most welcome…
Why did you take the values to 4 decimal places?
Thank u mam'
Most Welcome…
