The number N, in millions, of hearing impaired individuals of age x can be approximated by:
N = -0.00006x^3 + 0.006x^2 – 0.1x + 1.3

Approximate to the nearest million the number of hearing impaired individuals of ages 50 – 60.

N = (squiggly lines) ___________ million individuals of age 50.

N = (squiggly lines) ___________ million individuals of age 60.
