f(x)= -3/2x + 11
to find f(-8), substitute with x = -8
so, f(-8) = -3/2 * -8 + 11 = 12 + 11 = 23
==============================================
the second function:
g(x) = x^2 - 7x
so, g(-2) = (-2)^2 - 7 * -2 = 4 + 14 = 18
==============================================
the last function:
h(x) = | 15 - 9x |
so,
h(2/3) = | 15 - 9 * 2/3 | = | 15 - 6 | = | 9 | = 9
