Question

Find the domain and range of the function. 13. f(x) = 4x2

Answer 1

The function is given

`f(x)=4x^2`

The domain of the function is defind as the set of values of x for which the function is defined.

Hence the domain of the function is

`D=(-\infty,\infty)`

Here , x belongs to real numbers.

The range of the function is defined as the values of y for which the function is defined .

`R=\lbrack0,\infty)`

Here y is greater than equal to zero.
