Question

find the domain of the function
g(x)=2/8-7x
(fraction 2 is numerator 8-7x is denominator)

Answer 1

Domain refers to all values of x that give a real solution (not imaginary and not infinity)
Therefore, the only times that this would not give a real solution would be when the denominator is 0, so that means:

8 - 7x = 0
x = 8/7

Therefore, the domain is all real numbers except for 8/7
