Question in Standard Maths
Students are shown a graph of the value of a machine over time. The line equation is randomised.
They are asked to evaluate value at a given time, and the time at which a given value is reached. They are asked when the machine has no value, and the range of times over which the model is valid. They are also asked to explain the physical meaning of the gradient.
