the absolute value function, f(x) = –|x| – 3, is shown. what is the range of the function? all real numbers all real numbers less than or equal to 0 all real numbers greater than or equal to –3 all real numbers less than or equal to –3
The range is all real numbers less than or equal to –3
Answer:
Range is : all real numbers less than or equal to –3
Step-by-step explanation:
Range of a function f(x) is defined as set of all real possible values of f(x) such that the function is defined.
the given function is : -|x| - 3
Now, since absolute function only writes positive value so least value of |x| is 0
⇒ Greatest value of -|x| - 3 is -3
And least value is not fixed So the least possible value of f(x) is -∞
So, the range of f(x) is (-∞,-3]
Hence, Range is : all real numbers less than or equal to –3
