Find the inverse function

Mathematics
1 answer:
Alex3 years ago
3 0

The inverse of this function is f(x) = \frac{3x + 15}{4}


To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.


f(x) = \frac{-15 + 4x}{3} ----> Switch the x and f(x)


x = \frac{-15 + 4f(x)}{3} ----> Muliply both sides by 3


3x = -15 + 4f(x) ----> Add 15 to both sides


3x + 15 = 4f(x) ----> Divide both sides by 4.


f(x) = \frac{3x + 15}{4}

Answers

1) 4

2) 0, 2, -10

3) 0, 5, -2

Step-by-step explanation:

1) x³ - 64 = 0

x³ = 64

x = 4

2) x³(x² + 8x - 20) = 0

x³(x² + 10x - 2x - 20) = 0

x³(x(x + 10) - 2(x + 10)) = 0

x³(x + 10)(x - 2) = 0

x = 0, 2, -10

3) x³ - 3x² - 10x = 0

x(x² - 3x - 10) = 0

x(x² - 5x + 2x - 10) = 0

x(x(x - 5) + 2(x - 5)) = 0

x(x - 5)(x + 2) = 0

x = 0, 5, -2

Place the correct coefficients<br> x²y³ +<br> in the difference.<br> xy² +<br> y
antiseptic1488 [7]

The difference between the two polynomials is 11x²3y³ - 4xy².

<h3>What is the Difference between the Polynomials?</h3>

The difference between two polynomials is the result you get by subtracting one from the other.

Thus:

= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)

= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y

= 11x²3y³ - 4xy²

It has two what y equals so idk which one to solve or plug in(...I'm running out of points...)
Virty [35]
Just plug in one of the other (doesn't matter which one) so it will look like
-3x+6=5x+38
or
5x+38=-3x+6 (it's the same thing as the first one)
Then you solve for x and you substitute that value so you can get y.
Hope this helped :)
