It would be choice b.
The domain is the range of x values which in this case is from -5 to 3.
0.1 × 60,000 = 10x. Combine the terms on the left side of the equation.
6,000 = 10x. Divide each side by 10.
600 = x
As a fraction it would be 388888/100000.
For this, you just need to divide. 6/2=3, 90/2=45, and 100/2= 50. 50+45=95, 95+3=98
Hope this helps!
