Answer:
The vertex is (3,1)
Step-by-step explanation:
One way to solve this is to revert to integers.
Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)
Now you have 1,300,000 & 680000. Subtract to get 620,000.
Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5
We have 6.2 x 10^5.
It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
15 times 2.2 equals 33 and 21 times 2.2 equals 46.2 you would then multiply 33 by 46.2 and you would get 1024.6
