Question: Solve each problem that uses a logistic function. As age increases, so does the likelihood of coronary heart disease (CHD). The fraction of people x

Solve each problem that uses a logistic function.

As age increases, so does the likelihood of coronary heart disease (CHD). The fraction of people x years old with some CHD is modeled by f(x) = 0.9 1 + 271e -0.122.x

(a) Evaluate ƒ(25) and ƒ(65) to the nearest hundredth. Interpret the results.

(b) At what age, to the nearest year, does this likelihood equal 50%?

f(x) = 0.9 1 + 271e -0.122.x
