Solve each equation: 1. If f(x) = 3x - 12 what is the value when f(8)
and f(-5)
and f(-4)
2. If f(x) = 5(x - 7) + 2 what is the value when f(9)
and f(-3)
3. If f(x) = 2(x - 8) - 3 what is value when f(7) -
and f(-6)
4. If f(x) = 1/3(x - 6)2 + 4 what is the value when f(3)
Direct variation: what comes first is on top.
5. Suppose x varies directly as y, and x = 10 when y = 40. Find x when y - 120. X-
6. Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42. X =
