4 The function f() = 198.6 - xl. represents a person's variance from normal body temperature, where x represents a person's current body
temperature in degrees Fahrenheit. Medical professionals say healthy
individuals should have a variance of no more than 0.5°F.
Part A: What can be said of an individual with a body temperature of
99.4°F Justify your answer.
Part B: What can be said of an individual with a body temperature of
98.4°F Justify your answer.
Part C: What is a reasonable domain that would indicate the individual is
not healthy?

what type of question is thiss

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer: b f g .
