1.1. Complete the table of values for

$y=0.{5}^{(\frac{x}{3}+1)}+2$

giving each value to 2 decimal places where appropriate.

1.2. On the grid opposite, draw the graph of $y=0.{5}^{(\frac{x}{3}+1)}+2$ for $-6⩽x⩽0$

1.3. By drawing a suitable straight line on the grid, obtain an estimate, to one decimal place, of the root of the equation

${log}_{2}(2x+2{)}^{3}+x+3=0$ in the interval $-6⩽x⩽0$
