Hi Softballgirl6! I would say that first, we could pretend that the zeros don't exist because we could add those in later. Then just working with 1x2x3x4, we could mentally solve this to 24 and then add in the extra 4 zeros that we left out at the beginning. This brings the answer to 240000. Hope this helps! :)
So it's volume vs water filled graph
- Higher the volume higher the radius
For this y should be highest
Observe all 4
In set 1
- The line is more stepped towards y axis means y is higher
So set 1 has highest volume
Hence it has greatest radius
The equation is proportional and the slope is 2/7. y is 0 so you go 2 right and 7 up, keep repeating this. if you want it to go down to be a full line, start at y and go 2 left and 7 down

Answer:
3x² - 7
Step-by-step explanation:
3 times (number squared) and sum with (-7)
3 times x² and add (-7)
3x² + (-7)
3x² - 7
