1: sketch the curve y=x^2-4 (State the principles of graphing you have used)
Pick values for x and find y.
Plot the points (as many as you like) then draw a curve thru them.
===================
2:A scale of 4cm represent 18km on the ground.
find the scale of the map in form of a ration This scale will be represent
---
18 km = 18000 meters = 1800000 cm
Scale is 4:1800000 = 1:450000
