Question

Suppose f(x)=3x(x-1)/x²-3x+2 for x≠1,2,f(1)= -3,f(2)=4 then f(x) is continuous

Answer 1

Answer:

Let us assume that 3+5 is a rational number.

Now,

3+5=ba [Here a and b are co-prime numbers]

5=[(ba)−3]

5=[(ba−3b)]

Here, [(ba−3b)] is a rational number.

But we know that 5 is an irrational number.

So, [(ba−3b)] is also a irrational number.

So, our assumption is wrong.

3+5 is an irrational number.
