1. Determine all real zeros (roots) exactly (do not round) of the following quadratic functions. Justify all of your answers completely, solving for the roots by hand. No credit for: roots without justification or rounded roots (such as writing 0.33 when the root is 1/3). (a) a(x) = -4x+8 (b) b(t) = (t e) +5 (c) c(z) = (z+1) (d) d(w) = 4w + 2w 1
