WebExponentials & Logs A function of the form below is called an exponential function to the base a where a > 0 . For a > 1, the graph (sometimes called a growth function) will look like . For a < 1, the graph (sometimes called a decay function) will look like . The graphs always passes through (0, 1) and (1, a) Logarithms WebGCSE Higher The quantity of heat required to heat an amount of water is given by the formula: $$H = atI^2 – b$$ Where \(H\) is the number of calories delivered by an electric current of \(I\) amps acting for \(t\) seconds and \(a\) and \(b\) are constants. (a) Rearrange the formula to make \(I\) the subject. WebGCSE Exam paper practice question for AQA Higher Unit 3 Question 15 - exponential graphs Example: 1000 bacteria are put into a Petri dish.
