Question

What are the domain values for the function f(x) = 2x + 3 if the range values are (-1, 1, 2,4}

Answer 1

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

So i think it will be -1
