Higher November 2018 Paper 2 Q14
14 On the grid, sketch the curve with equation \(y = 2^x\)
Give the coordinates of any points of intersection with the axes.
(2)
| Answer | Mark | Mark scheme |
|---|---|---|
| curve | C1 | sketch of graph which starts above \(x\)-axis for negative \(x\), and makes an increasing exponential rise into positive \(x\) |
| (0,1) labelled | C1 | for showing a label of (0,1) on the \(y\) axis |
Additional guidance
Condone graph “touching” the \(x\) axis.
Do not award from a graph for positive \(x\) only.
Do not award if a point is given for crossing the \(x\)-axis. Accept the coordinates shown as a label of “1” written on the \(y\) axis at the intersection.
