Question

How do you find the domain and range of `(x-3) (3x-2)`?

Answer 1

Both the domain and the range are `-oo` to `+oo`.

Explanation:

The function is `= 3x^2 - 11x +6`

The domain is defined as any value of `x` that if you plug in the eq, shall give you a real value of the function.

So if you plug any value of `x` above, you will get a real value.

The range is defined as the set of values obtained by plugging in the values of the domain of the function.

Thus, domain and range are both are all real numbers.
