(gof)(4) is short for first find f(4) can you find f(4) ?
phi
  • phi
f(x)=x^2+3 f(4) is short for, "replace x with 4, and simplify"

oh okay..i kinda get it...

f(x)=x^2+3 are you saying when x is replace with 4, like this f(4)= 4^2 +3 you get 15 ? is your calculator broken?
phi

(gof)(4) is short for first find f(4) can you find f(4) ? if you can, make that number x in g(x) g(x)=x+5/x to find (g o f)(4)
anonymous

no but ive been doing this work for like 2 1/2 hours.. this is the last one
phi
  • phi
what do you get for f(4) ?
phi
  • phi
what do you get for f(4) ? f(4)= 4^2 +3 what is 4*4 ? and then add 3. what do you get ?
