Does anyone know how to do this? I’m lost

Nataly [62]

Answer: B

Step-by-step explanation:

To find the inverse function, you switch x with y and y with x. Then, you solve for y.

$y=(x-1)^{2} -4$ [switch x with y, and y with x]

$x=(y-1)^2-4$ [add both sides by 4]

$x+4=(y-1)^2$ [square root both sides]

$\sqrt{x+4} =y-1$ [add both sides by 1]

$\sqrt{x+4} +1=y$

$f^-^1(x)=1+\sqrt{x+4}$

Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.

What is the equation of the given line in standard form using integers coefficients y equals -1.7 x + 8.5

sukhopar [10]

If you want integer coefficients only, multiply the equation of the line by 10. I'm assuming you accidentally left off the "= 0" at the end: -1.7x + 8.5 = 0.

If that's the case, then multiplying the whole equation by 10 results in -17x + 85 = 0.

Here you have only integer coefficients.
