Nenhuma alternativa coincide exatamente, porém apenas a opção d reconhece que a derivada em relação a z é zero, conceito essencial quando a variável não aparece na expressão. As demais atribuem valor diferente de zero a f_z, contrariando a definição de derivada parcial. Por isso a alternativa d é a que melhor representa o resultado correto.","

Leia o trecho a seguir:

A função da derivada parcial em relação a um valor x_i é a derivada de f em relação a x_i uma vez que admitamos todas as outras variáveis como constantes.

Considere a função: f(x,y,z) = 3x + 5y. Derivadas parciais, ao calcular as derivadas parciais da função acima, obtemos:
