Question

Dada à função do 1°grau F (x)=1-5x. Determine:
a) F (0) b) F (-1)

Answer 1

F(x) = 1 - 5x

a) F(0) b) F(-1)

F(o)
====

F(x) = 1 5x

F(0) = 1 - 5(0)

F(0) = 1 - 0

F(0) = 1


F(-1)
====

F(x) = 1 - 5x

F(-1) = 1 - 5 (-1)

F(-1) = 1 - (-5)

F(-1) = 1 + 5

F(-1) = 6

Answer 2

Vejamos :

F(X) = 1 - 5X o foco

A) (0)

Y = 1 - 5 . 0
Y = 1 - 0
Y = 1

B)

Y = 1 - 5 (-1)
Y = 1 - (-5)
Y = 6
