The interval of increase of the function f space left parenthesis x right parenthesis equals x minus e to the power of x plus t a n invisible function application open parentheses fraction numerator 2 pi over denominator 7 end fraction close parentheses is

The given function is f open parentheses x close parentheses equals x minus e to the power of x plus tan open parentheses fraction numerator 2 pi over denominator 7 end fraction close parentheses
A function is said to be increasing when it’s first order derivative is positive.
It means f’(x) > 0
We will use this condition to find the answer.
Taking the first order derivative of the given function.
f(x) = x minus e to the power of x plus tan open parentheses fraction numerator 2 pi over denominator 7 end fraction close parentheses
f’(x) = 1 – ex + 0

Now for the function to be increasing,
f'(x) > 0
1 - ex > 0
1 > ex
e< 1
Taking loge of both the sides. It means we are taking natural log on both the sides.
xlogee < loge1
x < 0           ...{ logee = 1 and loge1 = 0}
x can have any value less than zero.
There is no lower limit on x.
So, the interval will be (-∞,0)
