Question

Convert the given mapping diagram into a graph of a linear function$f:R\to R$

• A.
• B.
• C.

Answer 1

The correct option is A

It is given that the function is linear.
Hence, it is a straight line.
To draw a straight line we need at most two points in the coordinate plane, i.e., two ordered pairs.

Let's take the ordered pairs $(4,-1)$ and $(-2,-3)$ as per the given mapping diagram.
Plot these two ordered pairs in the coordinate plane and connect them to obtain the graph.

From the graph we can find that the line passes through $(1,-2),$ hence (b) is the possible option.
