If f(x) and f-1(x) are inverse functions of each other and f(x) = 2x+5, what is f-1(8)?
Alexandra [31]

Answer:

B. 3/2

Step-by-step explanation:

If f(x) and f^{-1}(x) are inverse, that means that if we switch the x and y for f(x) and solve for y, we will get the inverse function.

Knowing that f(x) = 2x + 5, let's write this as y = 2x + 5 and switch the x and y:

x = 2y + 5

Now, solve for y:

x = 2y + 5

x - 5 = 2y

y = (x - 5)/2

That's the f^{-1}(x) function: f^{-1}(x)=\frac{x-5}{2}

Plug in 8 for x:

f^{-1}(x)=\frac{x-5}{2}

f^{-1}(8)=\frac{8-5}{2}=3/2

The answer is thus B.

inessss [21]

Answer:

the correct option is p≥75

Step-by-step explanation:

the correct answer ir p≥75 because the sum of all other task she have done

$150+$65+$120+$100+$90=$525 so in order to reach $600(the amount she needs to pay her bills) u need to rest:

$600-the sum of the other 5 works ---> $600-$525=75 ----> this means that $75 is enough to pay her bills, but if she earns more than that it would be enough too.

ANWER= p≥75(higher or equal to 75)

Arrange the functions in ascending order, starting with the function that eventually has the least value and ending with the fun
IRINA_888 [86]

The functions have been arranged in ascending order from the least to the highest value below

  • 3x
  • 3x + 8
  • x^2
  • x^2 + 6
  • 4^x
  • 4^x + 3

<h3>What is meant by ascending order?</h3>

This is used in mathematics as well as other disciplines to explain the order by which values are arranged. This arrangement is usually done in such a way that the smallest value would come first and continue to climb till we get to the value that is the highest.

The values here have been arranged in this order in such a way that the smallest values came first while the bigger values are at the end.

0.2 repeating is 0.222222222222 ...

Least:  0.125

Middle:  0.25

Greatest:  0.222222222222 ...
