Question

Determine the domain and range of the given function. The domain is

a) all real numbers
b) all real numbers less than or equal to -2
c) {x:x= -2,-1,0,1,2}
d) {y:y = -2,-1,0,1,2}

Answer 1

The range of a function represents the set of all possible output values or y-values for the function. The domain of the function is [0,20] and the range is a single value.

Step-by-step explanation:

The domain of a function represents the set of all possible input values or x-values for the function.

In this case, the function is defined for all values between 0 and 20, inclusive.

So, the domain of the function is the interval [0,20].

The range of a function represents the set of all possible output values or y-values for the function.

In this case, since the graph of the function is a horizontal line, the output value or y-value remains constant.

Therefore, the range of the function is a single value.
