Best ResponseYou've already chosen the best response.0Given f(x)= 3+2/x and g(x)= 1/x find f_g, fg, fg, and f/g. Determine the domain for each function.

Best ResponseYou've already chosen the best response.0I only need help with the last one. f/g. I got 3x+2/1 the system is telling me its correct but not fully simplified.

Best ResponseYou've already chosen the best response.2f(x) divide by g(x) \[\huge\rm \frac{ \frac{ 3+2 }{ x } }{ \frac{ 1 }{ x } }\] now solve

Best ResponseYou've already chosen the best response.0I need to simplify that further so how.

Best ResponseYou've already chosen the best response.2well the question u posted above is f(x) = 3+2/x

Best ResponseYou've already chosen the best response.0What? f(x)= 3+ 2/x g(x)= 1/x some*

Best ResponseYou've already chosen the best response.03+ 2/x over 1/x * x/x = 3x+2 all over 1

Best ResponseYou've already chosen the best response.2alright \[\huge\rm \frac{ 3+\frac{ 2 }{ x } }{ \frac{ 1 }{ x } }\] equal \[\frac{\frac{ 3x+2 }{ x } }{ \frac{ 1 }{ x } } = \frac{ 3x+2 }{ x } \times \frac{ x }{ 1 } = 3x+2\] that's it

Best ResponseYou've already chosen the best response.0Alright. Thank you. For f(x)= 2x5 and g(x)= 4x^2 4 D. (g*f)(1)

Best ResponseYou've already chosen the best response.2according to the previous post i guess * means compose like (g o f)(1) so first find f(1) substitute x for 1 into f(x) function or in other words you have to find g(f(1))

Best ResponseYou've already chosen the best response.2but if it's a multiplication sign then it would be f(1) times g(1)

Best ResponseYou've already chosen the best response.2ye thats what i asked n the previous post (f * g)(x) isn't same as (f o g)(x) ^multiplication ^substitution

Best ResponseYou've already chosen the best response.2( g o f)(1) = g compose f of 1

Best ResponseYou've already chosen the best response.0Yeah sorry about that. Its super tiny on my screen so I assumed it was *

Best ResponseYou've already chosen the best response.2so for this question find (g o f )(1) = g(f(1)) substitute x for 1 into f(x) function then plugin the result into g(x) function

Best ResponseYou've already chosen the best response.0The picture shows the example I have.

Best ResponseYou've already chosen the best response.2alright so in the example first they solvved g(f(x) and then sub x for 1

Best ResponseYou've already chosen the best response.0That all turns into 16x^2 80x +96

Best ResponseYou've already chosen the best response.0And I just plug 1 in for x correct?

Best ResponseYou've already chosen the best response.2alright i'll trust the calculator yes right now replace x with 1
