Estou fazendo um problema de múltipla escolha. (Aqui, exibo duas das opções.) Estou tentando traçar parábolas usando pgfplots. Por que não está TikZcompilando meu código? Coloquei um %na frente das parábolas que gostaria de traçar para TikZcompilar o código.
Além disso, gostaria que a imagem ficasse alinhada com a margem esquerda. Digitei \hspace{\fill}após o final do tikzpictureambiente.

Aqui está uma resposta parcial. Você precisará então colocar isso em seu contexto. Pessoalmente, eu construiria cada imagem gráfica com a classe autônoma construindo uma 'biblioteca' de diagramas reutilizáveis. Então eu usaria \inputgraphics para colocar os gráficos onde necessário. Mas este código responde à sua pergunta. Porém, para obter as parábolas você precisará indicar corretamente o domínio e a janela gráfica. (Deixo a matemática para você.)
