Solve f(x)=g(x) approximately using intersections of polynomial, rational, radical, absolute-value, exponential, and logarithmic graphs.
Classify an exact root, guaranteed bracket, or inconclusive table interval
Problem
Let \(h~=~f~-~g\) be continuous on \([1,~2]\), with \(h(1)~=~-2\) and \(h(2)~=~3\). State the evidence, method, and strongest warranted root conclusion.
For the difference function, an intersection of the original graphs corresponds to an output of zero. We’ll compare the endpoint signs and combine that evidence with the stated continuity, then use the Intermediate Value Theorem to decide the strongest warranted root claim. Finally, we’ll distinguish what the evidence guarantees from what it does not establish about exact location or uniqueness.
