Question 400586: I am having a hard time with this word problem:
Consider that the, x, of a unicorn in human equivalent yrs can be given by the formula f(x)=0.002718x^4+0.097326x^3-1.3367x^2+12.46x+3.914. When a unicorn is 2.5 yrs old, what is the age in human equivalent yrs? What about when it is 12 yrs old?

You can put this solution on YOUR website!
f(x)=0.002718x^4+0.097326x^3-1.3367x^2+12.46x+3.914.
-------------------
When a unicorn is 2.5 yrs old, what is the age in human equivalent yrs? What about when it is 12 yrs old?
Sub 2.5 for x
f(2.5) = 0.002718*2.5^4+0.097326*2.5^3-1.3367*2.5^2+12.46*2.5+3.914
Now it's just arithmetic.
--------------------
Do the same for f(12)
-------------------
Why do you call that a word problem?
