Question4) Individua quali fra i seguenti punti non appartengono al grafico della funzione f(x)=1x2xf(x)=\frac{1-x^{2}}{x} [a] (1;0)(1 ; 0) (b) (0;1)(0 ; 1) [C] (2;32)\left(-2 ; \frac{3}{2}\right) (motiva la risposta) [i] (1;0)(-1 ; 0) [e) (3;103)\left(-3 ;-\frac{10}{3}\right)

Studdy Solution
Evaluate f(x) f(x) at x=3 x = -3 :
f(3)=1(3)23=193=83=83 f(-3) = \frac{1 - (-3)^2}{-3} = \frac{1 - 9}{-3} = \frac{-8}{-3} = \frac{8}{3}
The point (3,103)(-3, -\frac{10}{3}) does not satisfy f(3)=83 f(-3) = \frac{8}{3} .
The points that do not belong to the graph of the function are (0,1)(0, 1) and (3,103)(-3, -\frac{10}{3}).
