Explanation

If a real root of f(x) = 0 lies in the interval, then the graph of f(x) must cross the x-axis between a and b.[a][b]

To cross the x-axis:

At one end the function value will be positive, f(a) > 0

At the other end the function value will be negative, f(b) < 0

When signs are opposite, their product is negative.

So f(a) × f(b) < 0
