What is the number of possible permutations of 8 objects taken 4 at a time? A. 24 B. 70 C. 1,680 D. 40,320

Graph the function \( f(x) = \sqrt[3]{x - 4} \) and identify its domain and range.

Para la función \( h(x) = \sqrt{5 - x} \), determina el dominio y explica cómo lo encontraste.

Find the number that makes the ratio equivalent to \( 12: 81 \). \[ : 27 \]
