What don't you understand?

2. zordoloom

Do you have a graphing calculator?

3. imnotblack

I'm terrible at math, and no I do not.

4. geerky42

Do you know what parent function (y = x²) looks like?

5. imnotblack

Nope. >.<

6. imnotblack

Can you help me?

8. cwrw238

thats the graph of y = x^2 (very roughly - lol!)

9. imnotblack

What does that have to do with the question?

10. cwrw238

we can transform y = x^2 to the graph on your diagram by 2 trasformations first reflecting it in the axis gives y = -x^2 |dw:1354197562913:dw|

11. cwrw238

then adding 1 to the function moves the whole graph 1 unit up the y-axis so can you see which option is correct graph?

12. imnotblack

is it A. j(x) = -x2 + 1? I'm horrid at math. >.<

13. cwrw238

yes thats right

14. imnotblack

Thank you. :)

x varies inversely as v, and x = 48 when v = 8. Find x when v = 64. A. x = 6 B. x = 64 C. x = 8 D. x = 48 It's 6 right?

17. cwrw238

yes
