f(x) = 4x^2 + 8x -3 Tentukan fungsi nya...

4x²+8x-3= 0
(2x+1) (2x+3)

dik : Rumus f(x) = 4x^2 + 8x-3
dit : fungsi ?

Jawaban :
f(x) = 4x^2 + 8x+3
f(1) = 4.1^2 + 8.1 - 3 = 4 + 5 = 9
f(2) = 4.4 + 8.2 - 3 = 16 + 13 = 29
f(3) = 4.9 + 8.3 - 3 = 36 + 21 = 57
f(4) = 4.16 + 8.4 - 3 = 64 + 29 = 93
f(5) = 4.25 + 8.5 - 3 = 100 + 37 = 37

semoga bermanfaat
