We know that According to Algebra of Real Functions :
If f and g are two real functions which are defined under the same domain then (f - g)(x) = f(x) - g(x)
Given f(x) = 
and g(x) = 
⇒ (f - g)(x) = f(x) - g(x)
⇒ 
⇒ 
First Option is the answer
Step-by-step explanation:
soln:
let,
(x1,y1) =(2,4)
(x2,y2)=2,-7)
Now,
By midpoint formula,
×= <u>x</u><u>1</u><u>+</u><u>x</u><u>2</u>
2
= <u>2</u><u>+</u><u>2</u>
2
=<u>4</u>
2
=2,,
And,
Y=<u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2
=<u>4</u><u>-</u><u>7</u>
2
= <u>-</u><u>3</u>
2
Hence ,
The mispoint between points (2,4) and (2,-7) is (2,<u>-</u><u>3</u><u> </u><u> </u><u> </u><u>)</u>
