-15 why cause ehe had 30 dollars and he first soent 20 such equals to 10 then he soends 25 such equals to -15
The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.
A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.
So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.
The domain is everything BUT those two values, because they essentially break your function.
(X+2)(y-5)=0
X+2=0
X=-2
Y-5=0
Y=5
X is horizontal
Y is vertical
First divided 25 and 8 and that well equal 3.124 so then multiply 3.124 and 100 that will equal 312.4%. Your answer will be 312.4%.
