Question

calcule as raizes e esboce o gráfico da seguinte funçao a) y=-x+5

Answer 1

Vamos lá

Resolvendo a tarefa:

Y = - X + 5
.

f ( - 2 ) = - ( - 2 ) + 5

f ( - 2 ) = 7

f (- 1 ) = - ( - 1 ) + 5

f ( - 1 ) = 6

f ( 0 ) = - 0 + 5

f ( 0 ) = 5

f ( 1 ) = - 1 + 5

f ( 1 ) = 4

f ( 2 ) = - 2 + 5

f ( 2 ) = 3
