We're given


\displaystyle \int_4^(-10) g(x) \, dx = -3

which immediately tells us that


\displaystyle \int_(-10)^4 g(x) \, dx = 3

In other words, swapping the limits of the integral negates its value.

Also,


\displaystyle \int_4^6 g(x) \, dx = 5

The integral we want to compute is


\displaystyle \int_(-10)^6 g(x) \, dx

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is


\displaystyle \int_(-10)^6 g(x) \, dx = \int_(-10)^4 g(x) \, dx + \int_4^6 g(x) \, dx = 3 + 5 = \boxed{8}
