Find the inverse of the function.

asambeis [7]

Answer:

A) $f^{-1}(n)= (n+2)^3$

Step-by-step explanation:

$f(n) = \sqrt[3]{n} -2$

$y = \sqrt[3]{n} -2$

$y = n^{1/3}-2$

$n = y^{1/3} -2$

$n + 2 = y^{1/3}$

$y = (n + 2) ^3$

$f^{-1}(n) = (n + 2)^3$

Hope this helps!

Help! The options are: proportional , not proportional

storchak [24]

Answer: Not proportional

=======================================================

Explanation:

Let's assume the two fractions are equal.

If so, then,

$\frac{0.2}{2.6} = \frac{0.3}{3.6}\\\\0.2*3.6 = 2.6*0.3\\\\0.72 = 0.78$

The last equation is false, so the first equation is false.

Therefore, the two ratios are <u>not</u> proportional.

-------------

Another approach:

Calculate the decimal value of each fraction

$\frac{0.2}{2.6} \approx 0.07692\\\\\frac{0.3}{3.6} \approx 0.08333\\\\$

The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.
