Write the polynomial in standard form then name the polynomial based on its degree 8-4x^2+10x^2+2x

I think it would be 6x^2+2x+8.

I hope this helps. :) 

in your graphing calculator you have to press the button (2nd) then (catalog) which is the number (0). 
after that you press (ALPHA) (L) which iOS the button for the parenthesis (. ).  )
find LOG and then plug in the number you want.
repeat this until you get the equation you want.
