I. True or false: I. x - 1 is a factor of a polynomial p(x) = 3x* -4x' + 5x] -4x+1 2. If p(x) is a polynomial of odd degree with real coefficients then p(x) must have at least one real zero 3. The polynomial p(x) = x* +x) -9x + 2x + 4 has a zero between 0 and I 4. The graph of a rational function may intersect its vertical asymptote 5. The graph of f (x) = _4 *+ 2 has two vertical asymptotes, x = 2, x= -2 6. If f (x) = x then f (x) = _ 7. log(xy) = logx -logy (x.y >0) 8. log(x+ y)= logx+logy (x.y>0) 9. Ine = log10 10. In1 + In2 = In 2 1 1. log-" = loga - logb + loge (a,b.c.> 0) 12. If f( x) = e' then f (x) = Inx
