Explicación paso a paso:
Se refiere a que obtengas el valor cuando x sea 0, 3, -4, 0.8 y -4/3
Entonces vas reemplazando:
x = 0.
0.5*0 -0.4*0² = 0
x = 3
0.5*3-0.4*3² = 1.5 - 0.4*9 = 1.5 - 3.6 = -2.1
x = -4
0.5*-4 - 0.4*(-4)² = -2 - 0.4*16 = -2 - 6.4 = -8.4
x =0.8
0.5*0.8-0.4(0.8)² = 0.40 -0.4*0.64 = 0.40-0.256 = 0.144
x = -4/3
0.5*-4/3 - 0.4*(-4/3)² = -⅔ - 0.4*16/9 = -⅔ - 32/45 = -62/45
