Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.

Debora [2.8K]

The inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$

<h3 /><h3>Domain and Range of functions</h3>

Given the function

$f(x) = 3(x - 2)^2 + 4$

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

$y= 3(x - 2)^2 + 4$

Replace x with y

$x = 3(y - 2)^2 + 4$

<h3>Make y the subject of the formula</h3>

$x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2$

Hence the inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$

All of the following are good reasons to attend postsecondary institutions except:

Ksivusya [100]

The best answer to the question would be (A) longer average life span.

Though there is a correlation between life span and education levels, where the higher your education, the higher your life span, other factors influence how long you life, most notably, of course your fitness levels, health, and diet. Thus, if you want to live longer, it is better to invest your time and effort into those three things instead of attending a postsecondary institution.
