Consider that the age,x,of a unicorn in human equivalent years can be given by the formula f(x)= 0.002718x^4+0.097326x^31.3367x^2+12.46x+3.914. When a unicorn is 2.5 years old, what is its age in human eqivalent years? What about when it is 12 years old?

Kourt,
You just have to plug 2.5 in for x in the equation to get the answer. Do the same with 12.
