Find f(g(x)) and g(f(x)) and the domain for both.
f(x) = 8x^2+12 g(x) = x/2x
Must use interval notation. When I tried posting the amswers earlier, ROBLOX blocked the post. So if you PM me your answer, then I will heck it against mine. The first one to solve it gets the robux. Anyone after that does not. |

| Lord, x doesn't need to be defined in this problem. I'm not asking for the value of x, but rather all possible values for x. |

| Incorrect Dull. Your answer must have the equation of f(g(x)) and g(f(x)) and use the correct interval notation. |

| It's not in the correct format, plus the equation needs to be shown as part of the answer. That's what the "Find f(g(x)) and g(f(x))" part was all about. |

f(g(x))
g(x)=x/2x g(x)=.5
f(.5)=8(.5^2)+12 f(.5)=8(.25)+12 f(.5)=2+12 f(.5)=14
Domain: Re Range: [14, 14]
I solved f(g(x)) |

g(f(x)) g(x)=x/2x // What x is doesn't matter, it will result in .5 // (gx) always = .5 Domain: Re Range [.5, .5]
Solved for the other. |
