The alternate way to solve the question is to put both the values of interval of the function. Then we compare the values. We also check if the first derivative is postive or negative. If it's negative, the given function is decreasing. And if postive, the given function is increasing.

Two long parallel wires carrying currents 2.5A and I amp in the same direction (directed into plane) are held at P and Q respectively as shown. The points P and Q are located at 5m and 2m respectively from a collinear point R. An electron moving with a velocity of $4 cross times 10 to the power of 5 end exponent m divided by s$ along positive x axis experiences a force of $3.2 cross times 10 to the power of negative 20 end exponent N$ at the point 'R'. The value of I is
