For the given functions f and g, find the requested function. Please show all of your work. f(x) = x+7; g(x) = 6x^2 - x. Find f - g.

Question

anonymous · Answer

$$f(x)-g(x)=(x+7)-(6x^2-x)$$ then algebra

anonymous · Answer

Can you please explain how you got this? thank you!

anonymous · Answer

i really just stuck a minus sign between the two functions

anonymous · Answer

it says to find f and g and Im so confused.lol

anonymous · Answer

but be careful with the parentheses

anonymous · Answer

the way i read the problem it GIVES you f and g and asks you to find 
$$f-g$$

anonymous · Answer

you wrote 
f(x) = x+7; g(x) = 6x^2 - x. Find f - g.

anonymous · Answer

Oh gotcha. Im so confused on this stuff.

anonymous · Answer

don't forget the distributive law when you remove the parentheses

anonymous · Answer

you should get 
$$x+7-(6x^2-x)=x+7-6x^2-x=-6x^2+7$$

anonymous · Answer

ok so is the first post you put considered the answer, or am i having to simplify further?

anonymous · Answer

i would write what i wrote at the end. you should do the algebra too so "final answer" would be 
$$(f-g)(x)=-6x^2+7$$

anonymous · Answer

i think you are confused on the next one as well yes?

anonymous · Answer

yes I am! lol- i really appreciate your help
