The only graph that can represent a cubic function is graph A.
Which of the graphs could represent a cubic function?
A cubic function is something like:
[tex]y = a*x^3 + b*x^2 + c*x + d\\[/tex]
Notice that the degree is 3, so it has 3 roots (crosses the x-axis 3 times). By looking at the given graphs, we can see that the only one that meets that condition is the first graph (counting from the left).
The other graphs are:
- B lineal.
- C quadratic.
- D lineal.
Then we conclude that the correct option is A.
