## True or False (1±√5)/2 are zeros of the function P(x) = 4x ^4 + 8x ^3 – 7x ^2 – 21x – 9

Answer: Step-by-step explanation: A logrithmic function is defined only for positive numbers. Irrespective of base, log function has domain always numbers greater than 0. Here given is log x to base 10. This is not defined for x =0 or x <0 x=0 will be an asymptote for log x. x<0 will not have any
