Oil is leaking out of a tank. The depth of oil in the tank for 60 seconds is shown below.

Use the graph to work out an
estimate for the rate of decrease
of depth, in cm/s, at 10 seconds.
You must show your working.

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
