Question

Dada a função afim f(x)=-2x+3,determine:f(1);f(0);f(2).

Answer 1

F(1)=-2×1+3= ( x=1, y=1)
F(0)=-2×0+3= (x=0, y=3)
F(2)=-2×2+3= (x=2, y=-1)

Answer 2

f(x)= - 2x + 3

f(1)

f(1)= - 2 • 1 + 3

f(1)= - 2 + 3

f(1)= 1

f(0)

f(0)= - 2 • 0 + 3

f(0)= 0 + 3

f(0)= 3

f(2)

f(2)= - 2 • 2 + 3

f(2)= - 4 + 3

f(2)= - 1
