Select the correct word to describe the function. the equation y = startfraction 5 x cubed over 8 endfraction represents functio

balandron [24]

The functions and their descriptions are:

Polynomial: $y = \frac{5x^3}{8}$ and $y = 5x^3 + 8$
Logarithm: $y = 6 + 0.25\ln(x)$
Exponential $y = \frac{18}{1 + 6e^{-0.25x}}$

<h3>How to describe the functions?</h3>

The functions are given as:

$y = \frac{5x^3}{8}$

$y = 6 + 0.25\ln(x)$

$y = \frac{18}{1 + 6e^{-0.25x}}$

$y = 5x^3 + 8$

The functions would be described based on the type of function they represent.

Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.

Answer: X=4

Step-by-step explanation:

Because the 90 angle is alternate exterior angle to the 21x+6. So they are equal to each other. It would be 90=21x+6. Then -6 to both sides to be 84=21x and 84/21 is 4. So X=4.
