Therefore the company's earning is 77 millions after 6 years.

Step-by-step explanation:

Given that,

The equation models the earning of a company is

y=x²+41

y = is revenue in millions

x = number of years since the company was founded.

The earning of the company is $77 millions.

To find the years, we need to put y=77 in the given equation.

⇒x²=36

⇒x=6

Therefore the company's earning is 77 millions after 6 years.
