Answer:
4
Step-by-step explanation:
6 times 12 is 72
72 divided by 18 is 4
1) 3/40
2) 13/22
3) -1/4
4)5/12
5)-3/16
6)-3/22
7)1/10
8)8/7
9)-7/6
Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)
Factor the denominator to find the excluded values of x...
3x^2+5x-12
3x^2+9x-4x-12
3x(x+3)-4(x+3)
(3x-4)(x+3)
So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:
x=(-oo, -3),(-3, 4/3),(4/3, +oo)
