Question 458628: I'm having trouble getting the answer to this:
Given that f(x) = square root 5-x, find f( 3.3).
When I do it I get the 1.308 but I don't get the 1.7 squared. Any help would be appreciated.

A)
square root 1.7≈ 1.3038

B)
square root 5 ≈ 2.2361

C)
square root 8.3≈ 2.8810

D)square root 1.7≈ 0.85

f%28x%29=sqrt%285-x%29


f%283.3%29=sqrt%285-3.3%29


f%283.3%29=sqrt%281.7%29 (note: simply subtract 3.3 from 5 to get 1.7)


f%283.3%29=1.3038 (note: this is approximate)


So the answer is A)
