Question

if ( k(x)=\frac{x^{3}+512}{x + 8} ), complete the table and use the results to find ( lim _{x
ightarrow-8} k(x) ).

complete the table.

(round to three decimal places as needed.)

Explanation:

Step 1: Substitute \(x = - 8.1\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK0 $$

Step 2: Substitute \(x=-8.01\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK1 $$

Step 3: Substitute \(x = - 8.001\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK2 $$

Step 4: Substitute \(x=-7.999\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK3 $$

Step 5: Substitute \(x=-7.99\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK4 $$

Step 6: Substitute \(x=-7.9\) into \(k(x)=\frac{x^{3}+512}{x + 8}\)

$$ LATEXBLOCK5 $$

Answer:

\(x\)\(-8.1\)\(-8.01\)\(-8.001\)\(-7.999\)\(-7.99\)\(-7.9\)

As \(x\) approaches \(-8\) from both sides, \(k(x)\) approaches \(192\). So \(\lim_{x
ightarrow - 8}k(x)=192\)
