Its simple, greatest value is c ---> a(x + b)^2 + c Here c = 25 hence its 25 when x is 2

I don't get functions

Functions, Coordinate geometry, Binomial expansion, Differentiation, Integration, Volume of revolution, Sector, Inequalities, Quadratics are my love

There you go bro

Thanks , but it didn't need that much working , it only carries one mark .
I got it by 1100 x 10 x ( 160/1760)x directly.

 

[Bilal Khan]

How do we solve This: e^2x = 1 / 5-e^0.5??

First , take ln on both sides .
ln (e^2x ) = ln (1/ 5-e^.5 )

2x = ln (1/ 5-e^.5 )

So x =( ln (1/ 5-e^.5 ) ) / 2 .
