Question

F(x) is the function that determines the absolute value of the cube of the input question: determine F(5) • F(-7) number 6 part 3

Answer 1

We know that F(x) is the funtion that determines the absolute value of the cube of the imput, this means that F(x) is defined as:

$F(x)=\lvert x^3\rvert$

Then:

$\begin{gathered} F(5)\cdot F(-7)=\lvert5^3\rvert\cdot\lvert(-7)^3\rvert \\ =\lvert125\rvert\cdot\lvert-343\rvert \\ =125\cdot343 \\ =42875 \end{gathered}$

Therefore F(5)*F(-7)=42875.
