Question

Plot the function $f:R\to R\text{where}2y=4-x$ and find whether it passes through (1.5, 3.5). Answer in Yes/ No.

Answer 1

The given function is $2y=4-x$ from set of real number to set of real number.
$\Rightarrow y=2-\frac{x}{2}$

Generate the ordered pair for plotting the graph. x y

0	1	2
2	1.5	1

The ordered pairs are $(0,2),(1,1.5),(2,1).$
Plot these ordered pairs and connect them with a straight line.
We can observe that the line does not pass over the point $(1.5,3.5).$
