Problema Solution
Consider that the age, x, of a unicorn in human equivalent years can be given by the formula f(x)= -0.002718x^4 + 1.3367x^2 + 12.46x + 3.914. When a unicorn is 2.5 years old. What is its age in human equivalent years? What about when it is 12 years old?
Answer provided by our tutors
f(x)= -0.002718x^4 + 1.3367x^2 + 12.46x + 3.914
Unicorn at 2.5 years old:
f(x)= -0.002718(2.5)^4 + 1.3367(2.5)^2 + 12.46(2.5)+ 3.914=43.312 years old
A 2.5 year old unicorn is approximately 43.312 years old in human equivalent years.
Unicorn at 12 years old:
f(x)= -0.002718(12)^4 + 1.3367(12)^2 + 12.46(12) + 3.914=289.558 years old
A 12 year old unicorn is approximately 289.558 years old in human equivalent years.
As you can see, to find the age of a unicorn in human equivalent years, all you have to do is plug in the age of the unicorn into the equation.
