Question

Let p be the number of real solutions of the equation 3^x+x-3=0 in the interval [0; 1] , and let q be the number of real solutions that are not in [0; 1]. Which of the following is true

a) p =0 and q =1;

b) p = 1 and q =1;

c) p =1 and q = 0 ;

d) p = 1 and q >1

Answer 1

One solution in the interval, 0.75.

Solutions not in the interval, 0, since the only solution is in the interval!
