Question

Dada a função f(x) = 4x + 1, determine: a) f(0) + f(-2) b) f(2) – f(3) + f(0) c) f(x) = -19

Answer 1

Resposta:

F(0) 4.0+1= 0+1= 1

F(-2) 4.(-2)+1= -12+1= -11

F(0)+F(-2)= 1+(-11)= +1-11= -10

F(2) 4.2+1= 8+1= 9

F(3) 4.3+1= 12+1= 14

F(2)-F(3)= 9-14= 5

F(x)= 4x+1=19= 4x+1-19= 4x-18

x= -18/4

x= -9/2
