Question

Given f(x) and g(x), approximate the following.(Round your answer to three decimal places.)
f(x) = x^3/(x^2+x+3) g(x) = ((sqrt5x) -x^3)^(3/2)
Find ((f + g)(1.14) - (f/g)(1.14)) / ([ (f o f)(5.6) ]^2)
(I tried this multiple times but I can't seem to get the right answer)

Answer 1

?

Answer 2

(f o f)(5.6) ]^2)

Answer 3

^ sure thats correct

Answer 4

its just calculator work, make sure you use brackets

Answer 5

I cant exactly help you with calculator work over the net

Answer 6

(f+g) = f(x) +g(x)

(f/g)(x) = f(x) / g(x) , when g(x) not zero etc

Answer 7

its fairly easy things to remember

Answer 8

The denominator is ((f of f) (5.6))^2

Answer 9

ok so that means its f ( f(5.6) )

Answer 10

I know how to do it but for some reason the answer is never right

Answer 11

so go to the expression for f , sub in 5.6 , then whatever you answer is , sub it back into f , and then sqaure whatever you get

Answer 12

yeah and then then the completed (f of f) answer is squared

Answer 13

its calculator work , just use brackets for everything
