Find the inverse function of h(x) = -2/3x + 6.

nalin [4]

Answer:

$h^{-1}(x)=-\frac{3}{2}x+9$

Step-by-step explanation:

To find inverse of a function, follow the steps below:

1. replace h(x) with y

2. Interchange x and y

3. Solve for the new y

4. Replace y to $h^{-1}(x)$ (this is the inverse function)

Step 1: y = -2/3x+6

Step 2: x = -2/3y+6

Step 3:

$x=-\frac{2}{3}y+6\\\frac{2}{3}y=-x+6\\y=\frac{-x}{\frac{2}{3}}+\frac{6}{\frac{2}{3}}\\y=-\frac{3}{2}x+9$

Step 4:

$y=-\frac{3}{2}x+9\\h^{-1}(x)=-\frac{3}{2}x+9$

This is the inverse function.

A: -50 B: -5 C: 2 D: 8

fiasKO [112]

Answer and explanation:

You're trying to figure out the value of x

If g(x) = 14 then that means that 4x + 6 = 14

4x + 6 = 14 Solve for x

- 6 - 6 Subtract 6 from both sides to get 4x alone

4x = 8  Divide 4x by 4 and 8 by 4

x = 2

Plug in 2 to see if it properly works

g(2) must equal 14

g(2) = 4(2) + 6

g(2) = 8 + 6

g(2) = 14

The answer would be C: 2

Find the sum and product of the roots of each equation of <img src="https://tex.z-dn.net/?f=x%5E%7B2%7D" id="TexFormula1" title=

Neko [114]

Answer:

$\huge\boxed{\sf S = 0, P = -16}$

Step-by-step explanation:

Given the equation:

$\sf x^2 -16 = 0$

Comparing it with $\sf x^2-Sx+P= 0$ , where S is the sum and P is the product.

So,

Sum = S = 0

Product = P = -16

Hope this helped!
