$(8p)f,[a,b]$ aral$ndatanml$ bir fonksiyon $ve{x}_0=0,x_1=0\mathrm{.}4,x_2=0\mathrm{.}7$ olsun. Buna $gre$

$f[x_2]=6,f[x_1,x_2]=10,f[x_0,x_1,x_2]=\frac{50}{7}$

iken $f[x_0]fis$ a function defined $ona,b$ and that $x_0=0,x_1=0\mathrm{.}4,x_2=0\mathrm{.}7.$ Suppose also that

$f[x_2]=6,f[x_1,x_2]=10,f[x_0,x_1,x_2]=\frac{50}{7}$

Find $\{$:$f[x_0].)$
