1.Given P(x)=x4+ax3+bx2+cx+dP(x) = x^4 + ax^3 + bx^2 + cx + dP(x)=x4+ax3+bx2+cx+d such that x=0x = 0x=0 is the only real root of P′(x)=0P'(x) = 0P′(x)=0. If P(−1)<P(1)P(-1) < P(1)P(−1)<P(1), then in the interval [−1,1][-1, 1][−1,1]a.P(−1)P(-1)P(−1) is the minimum and P(1)P(1)P(1) is the maximum of PPPb.P(−1)P(-1)P(−1) is not minimum but P(1)P(1)P(1) is the maximum of PPPc.P(−1)P(-1)P(−1) is the minimum and P(1)P(1)P(1) is not the maximum of PPPd.neither P(−1)P(-1)P(−1) is the minimum nor P(1)P(1)P(1) is the maximum of PPPLogin to continueOnly logged in users canattempt or see the solution.
