Answer:

<u><em>No, these functions fail to be inverses of each other.</em></u>

Step-by-step explanation:

We have two functions :

  • f(x) = 3x + 2
  • g(x) = \frac{x-2}{3}

Let's take the function f(x) and take x = 1.

  • f(1) = 3(1) + 2
  • f(1) = 5 [Keep this in mind]
  • If f(1) is 5, then if g(x) is an inverse function, g(1) should be \frac{1}{5}

Let's try the same with g(x).

  • g(1) = \frac{1-2}{3}
  • g(1) = -\frac{1}{3}

Clearly, they are not inverse functions of each other.

Which function is the inverse of f(x) = –5x – 4?
Finger [1]

Answer:

f^(-1)(x) = \frac{-1}{5} (x+4)

Step-by-step explanation:

Given is a function

f(x) = -5x-4\\

To find its inverse.

We must check whether f is one to one or onto first

If -5x1-4 = -5x2-4 we get x1=x2

Hence f is one to one

Also for every f(x) we can find a x so f is onto.

So inverse exists

Let

y=-5x-4\\-5x=y+4\\x=\frac{-1}{5} (y+4)

Replace x by f inverse and y by x

f^(-1)(x) = \frac{-1}{5} (x+4)

Help please. It’s supposed to be factored
Gnom [1K]

Answer:

p(q-1)

Step-by-step explanation:

P is the common factor in both the terms, so remove that to go outside the brackets.

What goes inside the brackets depends on what the quotient is when you divide both terms by p.

Hers,

pq becomes q

p becomes 1

THe negative sign remains there because he divide the is positive. (One positive and one negative make a negative)

Hope this helps

What is the inverse of f(x)=2x-6
saveliy_v [14]

Answer:

The inverse is 1/2x +3

Step-by-step explanation:

f(x) = 2x-6

y = 2x-6

Exchange x and y

x =2y-6

Solve for y

x+6 =2y

Divide by 2

1/2x +3 = y

The inverse is 1/2x +3
