Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = -2 and b = -1f(x) = 3x5 - 9x3 - 9x2 + 5
A. f(-2 ) and f(-1) have opposite signs, therefore the function f does not have a real zero between -2 and -1. B. f(-2 ) and f(-1) have the same sign, therefore the function f has a real zero between -2 and -1. C. f(-2 ) and f(-1) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between -2 and -1. D. f(-2 ) and f(-1) have opposite signs, therefore the function f has a real zero between -2 and -1.
Find the slope then describe what it means in the given situation.The linear function f(x) = -5.9x + 22 models the percentage of people, f(x), who eat at fast food restaurants x years after 2017.
A. m = 5.9; the percentage of people eating at fast food restaurants has increased at a rate of 5.9% per year after 2017. B. m = 22; the percentage of people eating at fast food restaurants has increased at a rate of 22% per year after 2017. C. m = -5.9; the percentage of people eating at fast food restaurants has decreased at a rate of 5.9% since 2017. D. m = -5.9; the percentage of people eating at fast food restaurants has decreased at a rate of -5.9% per year after 2017.
