Determine the function that is represented by f (x)= x² – 2x+5 A) {(-1,8)(0,5)(1,4)}
B) {(-1, -8)(0, - 5)(1,4)}
C) {(-1, 6) (0, 5)(1,4)}
D) {(-1,8)(0, 5)(1,8)}

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

yep b and c r the correct got it! : )
