Question 498908: Essay; show all work. Consider that the age, x, of a unicorn in human equivalent years can be given by the formula f(x) = - 0.002718x4 + 0.097326x3 – 1.3367x2 + 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?

Replace x with 2.5, then replace x with 12.

f(2.5) = 28.1242
f(12) = 72.7681

I swear, this question comes up a ton of algebra.com, and in my opinion it serves nearly no purpose because there are better ways to apply this mathematics.
