Question
On the grid below sketch the graph of the function \(f(x) = 2{(1.6)^x}\) for the domain \(0 \leqslant x \leqslant 3\) .
Write down the coordinates of the \(y\)-intercept of the graph of \(y = f(x)\) .
On the grid draw the graph of the function \(g(x) = 5 - 2x\) for the domain \(0 \leqslant x \leqslant 3\).
Use your graphic display calculator to solve \(f(x) = g(x)\) .
