Question

let f(x)=-7x-4 and g(x)=3x+5 Find f x g and its domain

Answer 1

So you need to compute the product of f and g:

(-7x-4)(3x+5)

Answer 2

what about the domain would it be all real numbers

Answer 3

the domain will be all real numbers except for your zeros :)

Answer 4

zeros are fine too here, there is no division here.

Answer 5

To find the domain of a function, you start with all real numbers and you exclude the numbers for which you divide by zero, get negative numbers under roots or get negative numbers in logarithms.

Answer 6

In this case there is no divisions, no roots or logarithms, so the domain is all real numbers.
