Select the correct answer. State the domain and range of the following function.

{(2,3), (7,9), (4,-7), (6,2), (3,-5)}
A.
Domain: {-7, -5, 2, 3, 7}; Range: {2, 4, 6, 9}
B.
Domain: {2, 2, 3, 4, 7}; Range: {-7, -5, 2, 9, 3}
C.
Domain: {2, 3, 4, 6, 7}; Range: {-7, -5, 2, 3, 9}
D.
Domain: {-7, -5, 2, 3, 9}; Range: {2, 3, 4, 6, 7}

all it means is function 3

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
