Higher June 2019 Paper 3 Q23
23 Here is a sketch of the curve \(\quad y = 2^x\)
On the axes above, sketch the curve \(\quad y = 3^x\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| Correct curve | B2 | B2 correct curve must be correct shape and pass through (0, 1) and be in correct position relative to \(y = 2^x\) B1 correct shape and pass through (0, 1) |
Additional guidance
Correct curve must be an exponential graph
Correct position must be
above \(\ y = 2^x\ \) for \(x > 0\)
below \(\ y = 2^x\ \) for \(x < 0\)
