Question

Select the correct function in the problem below.

Answer 1

If \[f(x)=\sqrt{x} \] and\[g(x)=\frac{ 2 }{ fx-3 }\] find \[(f \times g)x\]

Answer 2

Hint:

\(f \times g)x\) = \(f(x) \dot\ g(x)\)

Answer 3

How does that help? its just expressing the same thing as (f×g) X

Answer 4

It means to multiply both functions. Do I need to spell that out for you as well?

Answer 5

Yeah I know what it means. I just dont know how to combine the two equations, that part is befuddling me. I can see how they do it when theres multiplication or division or addition or subtraction but not when they dont tell you what to do to both equations to combine them.

Answer 6

\[g(x) =\frac{ 2 }{ 5x-3 }\] I made a mistake above.

Answer 7

Really? So you mean that if you see \(f(x) \dot\ g(x)\), you're telling me it is not obvious to simply multiply \[\left( \sqrt{x} \right)\left( \frac{2}{5x-3} \right)\]

Answer 8

No, I'm retarded. Feel better now?

Answer 9

I'll just ask my teacher she wont make me feel like a moron atleast.

Answer 10

Nobody is trying to make you feel like a moron. Whenever you're required to multiply functions f(x)*g(x), then this implies that the expressions that are equal to each function must also be multiplied.
