What is the domain of g (x) = 1-2x^2

Given Equation = > g (x) = 2x - 1

Now, the problem is we need to find the domain of g.

I believe that all domain are real numbers. Thus, let’s start finding the domain of g

Let’s try - 1 as the value of x

=> g (x) = 2x - 1

=> g (-1) = 2 (-1) - 1

=> g (-1) = - 2 - 1

=> g (-1) = - 3

Therefore, if the value of x is - 1, the domain value of g (x) is - 3

Let’s try 2 as value of x

=>=> g (x) = 2x - 1

=> g (2) = 2 (2) - 1

=> g (2) = 4 - 1

=> g (2) = 3

Therefore, if the value of x is 2, the domain value of g (x) is 2
