I need help asap (only the top part)

Domain: x0 or [0,infinity)

Step-by-step explanation:

f(x)= and g(x)=3-x

We are told to multiply the two functions so we multiply:

(fg)(x)=*(3-x)

(fg)(x)=3-x

Now this is a square root function and it can only go to the right because the square roots of numbers less than 0 are imaginary numbers. Therefore the domain must be greater than or equal to 0.

a negative exponent is translated as follows:

so, we have

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
