In this lesson, we explore how to locate the roots of an equation f(x)=0 using numerical methods. We'll learn how to identify intervals where a root exists by observing a change in sign of f(x). 📊

Through worked examples, students will learn to:

Sketch graphs to determine the number of solutions to an equation.

Show that a root lies within a given interval by evaluating f(x) at the interval's boundaries and checking for a change of sign.

Understand the conditions for a root to exist within an interval (change of sign and continuous curve).

Find solutions to a specified decimal place using a table function on a calculator.
