Question 8(b)
[Maximum number: 4]
The function f is defined by f(x)=5(x+1)(x+3), where .
Sketch the graph of y=f(x), showing the values of any intercepts with the axes and the coordinates of the vertex.
IB Maths AA SL 2.3 Graphing Functions
Practise sketching functions from equations or context, showing the correct branches, curvature and labelled intercepts, vertices, asymptotes and domain endpoints.
How this is tested
- calculate and label intercepts, turning points and other required coordinates before sketching
- draw the correct curvature and branches while respecting domain restrictions and asymptotes
- sketch and label related functions on common axes so shared and changed features remain clear
