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 $f(x) = g(x)$ .

Note: Award (A1) correct endpoints, (A1) for smooth curve.     (A1)(A1)     (C2)

$(0{\text{, }}2)$     (A1)     (C1)

Note: Accept $x = 0$, $y = 2$

Straight line in the given domain     (A1)
Axes intercepts in the correct positions     (A1)     (C2)

$x = 0.943$ ($0.94259 \ldots$)     (A1)     (C1)

Note: Award (A0) if $y$-coordinate given.
