Question

What is the range of the following graph? A. {xx 0,E R} B. {yly # 2, ER} C. {yl y = 0,9 € R} D. x + 2 x + R X" →X 0

Answer 1

The graph of the function is shown below

The range of a function is the set of all output values (Y-values).

From the graph, the graph is discontinuous on y= 0

Hence there is no output at y = 0

This implies that the range of the function is all real numbers except y = 2

That is

`\mleft\lbrace y\mright|y\\e2,y\in\mathfrak{\Re }\}`
