1.9.1 Locating roots by sign change (A-level only)

On the graph y=f(x)y=f(x)y=f(x), how does a root appear?

A

The function is strictly increasing or strictly decreasing throughout the interval.

B

The Intermediate Value Theorem.

C

Repeatedly testing an interval's midpoint to narrow the location of a root is called interval bisection.

D

It is an xxx-coordinate where the graph meets the xxx-axis.
