- Let f(x)= -6x + 3 and g(x) = 5x + 4. Find f•g and state its domain. A: -30x^2 - 9x + 12; all real numbers except x = 4

B: -30x^2 - 9x + 12; all real numbers

C: -18x^2 - 39x + 20; all real numbers

D: -18x^2 - 39x + 20; all real numbers except x = 1

The function is and the domain is all real numbers.

Step-by-step explanation:

Composition of functions is when one function is inside of another function.

The notation used for the composition of functions looks like this, .

We have the following functions

The composite function is

.

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

The function has no undefined points nor domain constraints. Therefore, the domain is or all real numbers.

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

x=6 and x=3
