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

    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|

    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?

    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?
