Given f(x) = ax2+ bx + c, where a = 3and b = 18, determine the line of symmetry x = C. Enter the value of C

c=y-3x^2-18x

axis of symmetry:

X=-3

Step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
