2. • 3 methods required
1. Decimal Search
2. Newton-Raphson
3. g(x) Rearrangement
• For each method we require success and
failure, and an accurate and detailed
illustration (graph)
3. The roots of the equation f(x) = 0 are equivalent to the
points at which the graph of y = f(x) crosses the x axis.
𝑥3 − 7𝑥2 − 6𝑥 + 40 an expression with
terms in powers of 𝑥
y = f(𝑥) is a function it cannot be solved, but
values can be explored𝑥 & 𝑦
f 𝑥 = 0 is an equation it can be solved and
the roots can be found
The solution consists of one or more roots
(one root is usually only part of the solution)
