Question

Show all work such as tables on finding the domain and range of k(x)= x^2+2x-3

Answer 1

The given function is:

`k(x)=x^2+2x-3`

The given function is a polynomial function.

Therefore, the function f(x) is defined for all real values of x.

Therefore, the domain of the function is: (-∞, ∞)

Using the table, the minimum value of the function is -4.

Therefore, the range of the function is: [-4, ∞)
