- In Exercises 7–10,find the two x-intercepts of the function f andshow that f '(x) = 0 at some point between the twox-intercepts. f (x) = x2 − x − 2arrow_forwardThe graph of f(x) below has a hole when x=_ and y=_arrow_forwardA researcher believes that if x thousand individuals among a susceptible population are inoculated (made no longer susceptible to a disease), then a function of form I(x)=a⋅R^x−b for constants a, b, and R would model the eventual number of infected individuals (also in thousands). Let R=0.9 (a) If the susceptible population is 5000 and no one is inoculated, how many will eventually be sick? . What point does that imply should be on the graph of the function I(x)? ( , ) (b) If the susceptible population is 5000 and everyone is inoculated, how many will eventually be sick? . What point does that imply should be on the graph of the function I(x)? ( , ) (c) Use the results of parts (a) and (b) to find approximate values for the constants a= ( ) and b= ( ) in the researcherâs model. (d) According to the model, how many susceptible individuals will be infected if half of them are inoculated?arrow_forward
