1)Is the following graph symmetric with respect to:

a)the x-axis b)the y-axis c)the origin

y=(x^2 - 4)/(2x^2)

2)Find the domain of

a)7Sqrt(x^3-1) ... it's the little 7 ontop of the sqrt, not 7 * sqrt

b)(2)/(x^2 + 6x + 9)

c)|x|+4

3)find the average rate of change of the f(x)= x^3 from 1 to 2x

4)if y=|x| then draw the following graph

a)y=|x+2|

b)y=|x| +4

c)y=|x+2| + 4

I realise that you won't be able to graph it in form of text so this is my e-mail european_footballstar@hotmail.com

Please show your work*

If anyone at all could help me I would really appreciate it and you'd be saving my life!! Desperate please help !
