Respuesta :

Domain : [tex](-\infty, \infty)[/tex]

Range: [tex](-\infty, \infty)[/tex]

Step-by-step explanation:

The function is [tex]d(t)=\frac{1}{2}t+6[/tex]

The domain of a function is the set of real numbers. Since, the function has no undefined points, the domain of the function is the set of all real numbers.

Hence, the domain of the function [tex]d(t)=\frac{1}{2}t+6[/tex] is [tex](-\infty, \infty)[/tex]

The range of a function can be found be substituting the values for x, the corresponding y-values can be determined.

Hence, the range of the function [tex]d(t)=\frac{1}{2}t+6[/tex] is [tex](-\infty, \infty)[/tex]
