Question

dada a funcao afim f(x)=-2x+3 determine f(-1/2)

Answer 1

f(x) = -2x + 3

f(-1/2) = -2 . (-1/2) + 3

f(-1/2) = 2/2 + 3

f(-1/2) = 1 + 3

f(-1/2) = 4

Answer 2

f(-1/2) eh soh substituir -1/2 no lugar de x

fika

f(-1/2)= -2.(-1/2) +3
f(-1/2)= (-2.-1)/2 +3
f(-1/2)= 2/2 + 3
f(-1/2) = 1 +3
f(-1/2) = 4
