Answer:
y = -(x-3)² -4
Step-by-step explanation:
no it is not correct. 18 divided by the sum of 3 and 3 equals 18 ÷ (3+3)
"sum of 3 and 3 " means 3+3 therefore 8/(3x3) = 8/9 and is completely different from the equation desired to be represented.
Look at the exponent and move the decimal that many places ( to the right for a positive number and to the left for a negative number)
