Question

Find f multiplied by g, and f divided by g. State any domain restrictions.
f(x) = -x^2; g(x) = 3x.
Can someone please explain this to me? I don't understand a thing!

Answer 1

f*g no restrciction in the domain, f*g=-3*x^3

Answer 2

f/g=-x²/3x, but can we divide a number by zero? so g(x), must be different form zero
this domain will be\[x \in R |x \neq 0\]

Answer 3

f/g= -x/3

Answer 4

@__mia_rachel__ get it?

Answer 5

Not at all.

Answer 6

HELP

Answer 7

what you dont get?

Answer 8

I don't understand ANYTHING. my teacher is horrible!

Answer 9

I don't even know what a function is -_-

Answer 10

for example f(x)= x² this function associate every number another number in this case the law of formation is this you pick a number and square it

Answer 11

the domain is all possible x that i can calculate that function

Answer 12

Whhaaatttt???
