Which description compares the domains of function a and function b correctly? function a: f(x)=? 3x+2

The domain of function A is all real numbers. There is no function B listed.

Step-by-step explanation:

The domain is the set of all x values. This is the set of all numbers which are inputs to the function. Since function A is a linear function y = 3x + 2, it has all real numbers as its domain. It has no restrictions.

There is no function B listed to compare.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
