.025 is the probability in decimal form.
2.5% in percent form.
Answer:
B. 3/2
Step-by-step explanation:
If f(x) and
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
function: ![f^{-1}(x)=\frac{x-5}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cfrac%7Bx-5%7D%7B2%7D)
Plug in 8 for x:
![f^{-1}(x)=\frac{x-5}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cfrac%7Bx-5%7D%7B2%7D)
![f^{-1}(8)=\frac{8-5}{2}=3/2](https://tex.z-dn.net/?f=f%5E%7B-1%7D%288%29%3D%5Cfrac%7B8-5%7D%7B2%7D%3D3%2F2)
The answer is thus B.
