Question

The function f(x)=90/1+270e^0.122x models the percentage, f(x), of people x years old with a certain disease. Use this function to evaluate f(35) and describe what this answer means in practical terms. f(35)=?(round to one decimal place

Answer 1

Given:

f(x) = 90

1 + 270e^-0.122x

W are asked to find f(35)

f(35) = 90

1 + 270e^-0.122(35)

f(35) = 90

1 + 270e^-0.122 * 35

Multiply the numbers: 0.122 * 35 = 4.27

f(35) = 90

1 + 270e^-4.27

f(35) = 90

1 + 270e^-0.122 * 35
