Question

for any x, 3 x + 1 is greater than 4 prove this statement is true​

Answer 1

Answer:

This statement is false if x is any number and true if x is an natural number.

Step-by-step explanation:

If x is any number then :

Let x = -3

Substitute and you get

= 3 x ( -3 ) + 1

= -9 + 1

= -8

Here -8 is lesser than 4.

If x is any natural number then :

Let x = 1

Substitute and you get

= 3 x ( 1 ) + 1

= 3 + 1

= 4

But here 3 x + 1 is equal to 4 and not greater than 4.

This statement is true for all natural numbers except 1 .

Hope this helps.
