24.6.3 Counting Zeros from the Graph

Core idea

Look at where an exponential curve, a log curve, or a line meet, and the number of crossings is the number of zeros.

Module goal. Unify the roots of equations through a function lens, master the existence theorem for zeros and the bisection method, laying groundwork for continuity and approximation
