Question

Can you find domain and range on an undefined function

Answer 1

You have the grpah of a quadratic function (a parabola).

A quadratic function is not a undefined function (all values of x have a corresponding value of y)

The domain of a function is all the x-values where the value is defined.

The range of a function is all the y-values that the fjunction takes.

For the given quadratic function:

Domain: It is defined for all real values of x

`(-\infty,\infty)`

Range: The function takes values greather than or equal to 2

`\lbrack2,\infty)`
