about the graph of e^x,, ya i know how to draw
but wat about the asymptote of e^x^2, would it be the y-axis itself, like for e^x?

yes. suppose you had e^a. where a=x^2.

4 (i) 12 ( -2 ) ³ + 25 ( -2 ) ² -4 ( -2 ) - 12 = 0
-96 + 100 + 8 - 12 = 0
108 - 108 = 0
Thus we have shown that f(-2) = 0

Second part I have no idea how to solve ^_^! But the closest answer I got is -0.368!

nightrider1993. This is incredible. Thanks mate.
Can you tell me where can i obtain some good illustrated examples of integration of functions whereby you have to use ln of denominator and doing multiplications accordingly?

Could someone help me to simplify this sum?

(2x^2 y^-1)^-1/4
____________
(8x^-1 y^2)^-1/2

 

[parthrocks]

Could someone help me to simplify this sum?

(2x^2 y^-1)^-1/4
____________
(8x^-1 y^2)^-1/2

The simplified answer for this one would be

x^3/ 8y^3---(x cube upon 8 y cube for better understanding )
If you want the method then just tell me I will attach a scan....take care...

 

[parthrocks]

and also let me know if I m wrong???please thank you...

Yes, pls..?

and also let me know if I m wrong???please thank you...

The book states the answer is 2^5/4 x^-1 y^5/4 .. but I dunno how to reach at this answer..
