Respuesta :
Domain will be all real numbers since no restrictions of x is present.
The range will be [4, +∞), because the minimum value of absolute function is 0

Answer:
Domain-- All the real numbers.
Range-- [4,∞)
Step-by-step explanation:
We are given a function f(x) as:
[tex]f(x)=5|x-2|+4[/tex]
We know that domain of a function is the set of all the x-values where the function is well defined.
Also, we know that the modulus function is defined for all the real numbers and hence adding a constant does not change the domain of the function.
Hence, Domain of function is all the real numbers.
Also, we know that:
[tex]|x-2|\geq 0\\\\5|x-2|\geq 0\\\\5|x-2|+4\geq 4\\\\i.e.\\\\f(x)\geq 4[/tex]
Hence, the Range is the set of all the real values greater than or equal to 4.
Hence,
Range= [4,∞)
