Quadratic Graphs
Recognise that quadratic functions produce curved (parabolic) graphs, distinguish them from linear graphs, and use plotted quadratic graphs to estimate values and find approximate solutions

Question 1 of 3
A graph of the quadratic function y = x² – 5 is drawn. The graph passes through the points (1, –4), (2, –1) and (3, 4). Based on this graph, which x‑value is the best estimate of where the graph crosses the x‑axis (where y = 0)?
Question 2 of 3
Below is a table of x‑values for the function y = x² – 4. Which one of these points would NOT appear on the graph of the function?
Question 3 of 3
The graph of a function includes the points (0,0), (1,1), (2,4), and (3,9). Which description best characterizes the functional relationship between x and y?
