State which of the following statements and true and which are false? Give reasons for your choice. (i) The degree of the polynomial sqrt(2) x^(2)-3x+1 is sqrt(2) .

The figures shows th variation of photocurrent i with anode potential V for three differential radiations. Let I_(a)I_(b)" and " I_(c) be the intensities and f_(a),f_(b)" and " f_(c) be the frequencies for the curves a, b and c respectively . Then

For the function f(x) = x^(x) , find the points at which it is (i) increasing and (ii) decreasing. Hence determine which of e^(pi), pi^(e) is greater.
