I am having trouble with this one.
consider that the age, x, of a unicorn in human equivalent years can be given by the formula f(x)=-0.001518x^4+0.097326x^3-1.2367^2+10.46x+2.914. when a unicorn is 2.5 years old, what is its age in human equivalent years? what about when it is 12 years old?

dumbcow · Answer

is x the age of the unicorn ?

anonymous · Answer

yes I think.. this one has me stumped

terenzreignz · Answer

Did you try just substituting 2.5 and 12 in your age function?

anonymous · Answer

so i would write it like this f(2.5)=then the equation

terenzreignz · Answer

Yes... 
I think, though I'm not sure...
that this isn't the kind of problem you'd want to solve without a calculator...
are you allowed them?

anonymous · Answer

yes

terenzreignz · Answer

Then key away :)
Just replace all the x's with 2.5
and then with 12 :)

anonymous · Answer

thanks have a great night

terenzreignz · Answer

No problem :)

anonymous · Answer

simply sustitute the values ......as f(2.5) and f(12)
