Best ResponseYou've already chosen the best response.3\[\frac{ f(5) }{ g(5) } = \frac{ 2(5)20 }{ 5 1 }\]

Best ResponseYou've already chosen the best response.3right , yeah it is f(5) / g(5), just evaluate both and put them over each other

Best ResponseYou've already chosen the best response.0given the functions f(x)and g(x), solve (f times g)(3) and select the correct answer below f(x)4x^2+12 g(x)=x1

Best ResponseYou've already chosen the best response.3ok, then it is a compound function f[g(x)]

Best ResponseYou've already chosen the best response.0so how would i set up the equation

DanJS

Best ResponseYou've already chosen the best response.3nope, it is gonna be multiplication

Best ResponseYou've already chosen the best response.0so i would multiply the 2 equation they gave me?

Best ResponseYou've already chosen the best response.0so (4x^2+12)3 and (x1)3?

DanJS

Best ResponseYou've already chosen the best response.3you could do that first, or put in the value for x to start, [4(3^2) + 12] * (31)

Best ResponseYou've already chosen the best response.0hows did you get the value of x

DanJS

Best ResponseYou've already chosen the best response.3THe problem says [f times g ](3) , x=3

DanJS

Best ResponseYou've already chosen the best response.3so you just evaluate both f and g at x=3 , then multiply the values together

Best ResponseYou've already chosen the best response.3I have time for one more if you want

Best ResponseYou've already chosen the best response.3f(3) * g(3) = [4(3^2) + 12] * (31) = 96

Best ResponseYou've already chosen the best response.0how did u get 96 i got 168

anonymous

Best ResponseYou've already chosen the best response.0ok and wat a bout the part when you multiply it by 31

DanJS
 one year ago
Best ResponseYou've already chosen the best response.3that is what happened, the 2 at the end... f(3) * g(3) = [4(3^2) + 12] * (31) = 96

anonymous

Best ResponseYou've already chosen the best response.0i get it now i messed up omewhere but i see thay why its a 2 at the end cuz 31 is 2 ok can u hepl with one more?

Best ResponseYou've already chosen the best response.0Given the following functions f(x) and g(x), solve f[g(6)] and select the correct answer below: f(x) = 6x + 12 g(x) = x − 8

Best ResponseYou've already chosen the best response.3These compound functions like that, you work from the inside most function first, then outwards carrying the values...

DanJS

Best ResponseYou've already chosen the best response.3figure out g(6), then use that value in f(x) for x

DanJS

Best ResponseYou've already chosen the best response.3yes, anytime you see g(#) or f(#) some number, that is what x is

Best ResponseYou've already chosen the best response.0k so now i plug it in dont tell me ill tell u n u tell if its right

DanJS

Best ResponseYou've already chosen the best response.3no... First , what is g(6) ?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0i did x8 and plugged 6 for x

DanJS
 one year ago
Best ResponseYou've already chosen the best response.3right, so g(6) = 6  8 = 2

DanJS
 one year ago
Best ResponseYou've already chosen the best response.3now you use that value you just got in the f function for x

DanJS
 one year ago
Best ResponseYou've already chosen the best response.3no, that is the thing with the compound functions, you have to use the value from g(6) = 2 for the value of x in f(x)

DanJS

Best ResponseYou've already chosen the best response.3Figure the inner function out, use that value in the next function

Best ResponseYou've already chosen the best response.0o ok so i plug the 2 in instead of the 6?

anonymous

Best ResponseYou've already chosen the best response.0can you explain how you get that from f(x)=6x+12?

DanJS

Best ResponseYou've already chosen the best response.3ok, start over from the beginning...

DanJS

Best ResponseYou've already chosen the best response.3f [ g(6) ] What that means is instead of having the usual f(x), you have f( another function) Start with the inner function g(6) and evaluate. g(6) = 2 Now you can replace g(6) with 2 in the original problem

Best ResponseYou've already chosen the best response.0so where do i go from here?

DanJS

Best ResponseYou've already chosen the best response.3just left to evaluate f(2) = 6*(2) + 12

anonymous

Best ResponseYou've already chosen the best response.0o ok so now u added the 6(2)+12 wouldnt it be 0

DanJS
 one year ago
Best ResponseYou've already chosen the best response.3so it is zero i have to take off, you can fan me , ill prolly be on later

anonymous

Best ResponseYou've already chosen the best response.0ok how do i fan you?
