Assessment: Linear Functions #0    due: day 1 of week 10

Do not lose this assessment. Do all your math on your own paper.

   f(x) = -2/3(x) + -3
   g(t) = 1.5(t) + 1
   h(x) = 0.125(x)
   z(a) = -7(a) - 7
   Q(x) = -3 + -2(x)

   a-e.  Record the slope, vertical-intercept and horizontal-intercept
         for the functions f(x), g(t), h(x), z(a) and Q(x).

   f.    f(2) = _____

   g.    g(0 + 0.5) = _____

   h.    h(8) * z(-1) = _______

   i.    f(0) + g(0) + h(0) + z(0) + Q(0) = ______

   j.    f(g(h(8))) = ______
