What is the domain of the function f(x)=x(x+4)

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
