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

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

Since x= 3/4 what do you think p and q equals? Before you try to answer that you simply need to know if 3/4 is in [0,1]
