For the curve y = 4/x, work out y when x = -1, and write down the equation of its vertical asymptote.
- 2Direct and Inverse Proportion3 marks
y is directly proportional to x. When x = 3, y = 30. Work out y when x = 2.
- 3Similar Shapes (Area and Volume)3 marks
Two similar shapes have lengths in the ratio 1 : 3. The smaller has an area of 3 cm^2. Work out the area of the larger.
