N = 00.00006x^3 + 0.006x^2 - 0.1x + 1.7. To nearest million,  TOPIC_SOLVED

I need some serious help! :confused:

The number N, in millions, of hearing impaired persons of age X can be approximated by N= -0.00006x^3 + 0.0006x^2 - 0.1x + 1.7. Approximate to the nearest million the number of hearing impaired persons ages 35 and 50.
