1.1. The table shows some values of  $y=\frac{{x}^{2}}{2}+\frac{1}{{x}^{2}}-\frac{2}{x}$, $x\neq0$.

  Complete the table.

1.2. On the grid, draw the graph of  $y=\frac{{x}^{2}}{2}+\frac{1}{{x}^{2}}-\frac{2}{x}$  for  $-3\leqx\leq-0.3$  and  $0.2\leqx\leq3$.

1.3. Use your graph to solve  $\frac{{x}^{2}}{2}+\frac{1}{{x}^{2}}-\frac{2}{x}\leq0$.

1.4. Find the smallest positive integer value of $k$ for which  $\frac{{x}^{2}}{2}+\frac{1}{{x}^{2}}-\frac{2}{x}=k$ has two solutions for  $-3\leqx\leq-0.3$  and  $0.2\leqx\leq3$.

1.5. By drawing a suitable straight line, solve  $\frac{{x}^{2}}{2}+\frac{1}{{x}^{2}}-\frac{2}{x}=3x+1$  for  $-3\leqx\leq-0.3$  and  $0.2\leqx\leq3$.
