Question

9) Determine the domain and range of the function represented in the graph. A. Domain: – 1

Answer 1

we know that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y

so

In this problem

The domain is the interval {-1,3}

so

`-1\leq\text{ x }\leq3`

The range is the interval {-4,5}

so

`-4\leq\text{ y}\leq5`

answer Option A
