if f(x)=int(2x) find f(1.2)

Does "int" mean "integral of" or INT (the integer function)? I am going to have to guess.

INT (x) is the greatest integer that is less than or equal to x. If x = 1.2, 2x = 2.4 and INT(2.4) = 2

To find f(1.2), substitute the value of 1.2 into the function f(x) = int(2x) and perform the calculation.

First, multiply 1.2 by 2: 2 * 1.2 = 2.4

Then, take the integer part of 2.4. Since the integer part function int(x) rounds down to the nearest whole number, the integer part of 2.4 is 2.

Therefore, f(1.2) = 2.

To find f(1.2), we need to substitute 1.2 into the function f(x) = int(2x), where int(x) represents the greatest integer less than or equal to x.

So, we substitute x = 1.2 into the function:

f(1.2) = int(2 * 1.2)

Now, we need to find the greatest integer less than or equal to 2 * 1.2.

The value of 2 * 1.2 is 2.4. The greatest integer less than or equal to 2.4 is 2.

Therefore, f(1.2) = 2.
