We want to find the axis of symmetry of the function;

STEP 1:
The equation for the axis of symmetry of a line is given as;

From the equation, a = 6 and b = -3, so,
STEP 2: Insert the values of a and b into the equation to obtain;

CONCLUSION:
Therefore, we see that the axis of symmetry is the line;
Answer:
1, -3, -5, -7, -11, -13, -15, -17?
Answer:
The Check that hasn't been cleared yet is for $372.15.
Step-by-step explanation:
168.48+ 168.93+ 177.78+ 177.93= 693.12
887.79- 693.12= 194.67
1,065.27- 887.79= 177.48
194.67+ 177.48= 372.15
To check your answer:
372.15+ 693.12= 1,065.27
Hope this helped you!! (:

and surely you'd know what the roots are
