jim_thompson5910 · Answer

does the graph open upwards or downwards?

jim_thompson5910 · Answer

If it opens upwards like this

|dw:1395529741230:dw|

then the leading coefficient is positive

mikezack123 · Answer

It opens downward

jim_thompson5910 · Answer

If it opens downwards like this

|dw:1395529779889:dw|

then the leading coefficient is negative
