Answer 1

Given,

the table for the different values of x and there function value is shown in table.

here,

The function value of f(-3.999) is 0.4002.

So,

$\lim _{x\to-4^-}f(x)=0.4002$

As, -3.999 is the closest value of -4 in negative.

Similarly,

The function value of f(-4.001) is 1.503999.

So,

$\lim _{x\to-4^+}f(x)=1.503999$

As, -4.001 is the closest value of 1.503999 in positive.

$\lim _{x\to-4^{}}f(x)=-4$

Hence, the value of lim x-> -4^- is 0.4001, lim x-> -4^+ is 1.503999 and lim x-> -4 is -4
