Question

(Can anyone help??!) A cross section of the parabolic glass mirror of the Hubble space telescope shown can be modeled by the graph of the function y = 0.0043x2 where x and y are measured in meters.

Find the domain and range of the function in this situation. (see attachment)

Answer 1

the domain are the possible values of x which is {-1.25, 1.25]
and the range are the y values [0 , 006]

or put another way domain is x >= -1.25 and <= 1.25
and range is y >= 0 and <= 0.006

Answer 2

Thanks .
