C = cost
C = 7.70 + 0.15n
-----------------
Let f(x) = x^2 - 7 an g(x) = 6x-2. Find the value, if possible. (If not possible, enter IMPOSSIBLE.)
(f+g)(-5)
f(-5) = (-5)^2 - 7 = 18
g(-5) = 6*(-5) - 7 = -37
f(-5) + g(-5) = -19
----------------------
Let f(x) = 4x-4 and g(x) = 4x-4. Find the value.
(g * f)(-6)
g(-6) = 4*(-6)-4 = -28
f(-6) = -28
f*g = 784</PRE>
