Two variables, x and y, are known to be related by an equation of the form $ y = Px^{4} + Q $, where P and Q are constants. In an experiment, the following values of x and y were recorded. (a) On the axes, draw a straight-line graph for y against $ x^{4} $. (b) Hence estimate the…

Two variables, x and y, are related by an equation of the form $ y = Ax^{b} $, where A and b are constants. The following pairs of values of x and y are given. (a) On the axes below, use these values to draw the straight-line graph of $ \ln y $ against $ \ln x $. [2]

Variables $y$ and $x$ are known to be connected by the relationship $y = Ab^{x}$ where $A$ and $b$ are constants. The table shows values of $y$ for certain values of $x$. (a) Draw the graph of lg y against x. [2] (b) Use your graph to find values of $A$ and $b$, giving each to 1…
