Answer: -12
According to the problem, y = f(x) = 2x
Here the value of x = 2.
We have to put the value of x in place of x in 2x to calculate the actual value of 2x.
Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4
This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.
Again the value of f(x) = 2x.
Therefore, the value of f(x) = 2x = 4.
