Question

What is the domain and range of the quadratic function given by the equation /(x) = 2(x-4)] - 2

Answer 1

The domain of the function is the set of all real numbers and the range of the function is the set of all values greater than -2

How to determine the domain and the range?

The function is given as:

f(x) = 2(x -4)^2 - 2

A quadratic function can take any real number as its input.

So, the domain of the function is the set of all real numbers

The vertex of the above function is:

Vertex = (4, -2)

And the leading coefficient is:

a = 2

The y value of the vertex is;

y = -2

Because the value of a is positive, then the vertex is a minimum.

This means that the range of the function is the set of all values greater than -2
