Which function represents the inverse function of the function f(x)= x^2+5

Step-by-step explanation:

we have the function

Let

step 1

Exchange the variables, x for y and y for x

step 2

Isolate the variable y

Subtract 5 both sides

step 3

Take square root both sides

step 4

Find the inverse

so

12 minutes

Step-by-step explanation:

In my brain, I divide the run into three parts (because the fraction has a base of three). If I ran two parts of those three in eight minutes, then to find the amount of time it took to run one part (cause that's how much we need to add), I need to divide the time by two, and then add it to the 8 minutes. When the math is done, a third of a mile can be ran in 4 minutes, which means that an entire mile can be ran in 12 minutes.
