Card 1 of 23
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.
