What is the inverse function of y = (x-4)^2+2

Mathematics
1 answer:
Talja [164]1 year ago
6 0

One way to find the inverse of a function is by first swapping x and y, then solving for y, like this:

\begin{gathered} y=(x-4)^2+2\text{ }\Rightarrow x=(y-4)^2+2 \\  \end{gathered}

Now, let's solve for y, like this:

\begin{gathered} x=(y-4)^2+2 \\ x-2=(y-4)^2+2-2 \\ (y-4)^2=x-2 \\ \sqrt[]{\mleft(y-4\mright)^2}=\sqrt[]{x-2} \\ y-4=\sqrt[]{x-2} \\ y-4+4=\sqrt[]{x-2}+4 \\ y=\sqrt[]{x-2}+4 \end{gathered}

Then, the inverse function of y = (x-4)^2+2​ is:

y=\sqrt[]{x-2}+4

Answer:

  The line of reflection is at y = x+6.

Step-by-step explanation:

The perpendicular bisector of AA' is a line with slope 1 through the midpoint of AA', which is (-4, 2). In point-slope form, the equation is ...

  y = 1(x +4) +2

Answer:

\frac{9}{11}

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have:

3 red cards

6 blue cards

2 green cards.

What is the probability that the card is not green?

3 + 6 + 2 = 11 cards, of which 3 + 6 = 9 are not green. So

\frac{9}{11} probability that the card is not green
