What is the inverse of the function fx=19/x3

Mathematics
1 answer:
laila [671]3 years ago
5 0

f(x) = \frac{19}{x^3}

Set f(x) = y and solve for x:

y = \frac{19}{x^3}

\frac{19}{y} = x^3

x = \sqrt[3]{\frac{19}{y} }

Now, switch the x and y:

y = \sqrt[3]{\frac{19}{x} }

Now, write it in the correct notation, and your answer is:

f^{-1}(x) = \sqrt[3]{\frac{19}{x} }

Hope I could help!

Find the missing section. Answers must be in fraction form.
frozen [14]

Answer:

\frac{1}{10}

Step-by-step explanation:

We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.

For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.

Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.

What times 5 equals 10?

2

Now multiply both numerator and denominator by 2 to get our portion.

\frac{4*2}{5*2}

\frac{8}{10}

Now we have the same denominator, let's add our two fractions and see how much we have left.

8/10 + 1/10

9/10

We have 1/10 missing, therefore 1/10 is the answer.

Which ordered pair is a reflection of (3, 7) across the y-axis?
worty [1.4K]

Answer:

(-3, 7)

Step-by-step explanation:

It is like putting a mirror on the y-axis. It is asking what point is the photo negative of the point, like a mirror. You see yourself in the mirror but everything is opposite. Your right hand is your left. So which point is the photo negative of (3, 7)? (-3, 7) Because it is only across the y-axis, the y value stays the same.
