 Hello friends welcome to the session I am Alka, I am going to help you solve the following question that is differentiate with respect to x the function in exercises 1, 2, 11. Of course exercises 3x square minus 9x plus 5 to the power 9. So let us start with the solution we are given 3x square minus 9x plus 5 e to the power 9. So let this be y. Now we will differentiate both sides with respect to x we get dy by dx equal to nx that is 9 into 3x square minus 9x plus 5 to the power 8 into dy dx of 3x square minus 9x plus 5 this implies dy by dx equal to 9 into 3x square minus 9x plus 5 to the power 8 into dy dx of 3x square will be 6x minus dy by dx of 9x will be 9. Therefore this implies dy by dx equal to 9 into 3x square minus 9x plus 5 to the power 8 into 6x minus 9. So hope you understood the solution and enjoyed the session. Goodbye and take care.
