Find the inverse of f(x)= -x + 3
inna [77]
Let g the inverse function of f.

The most important property of g and f being inverses of each other, is that 

g(f(x))=x,      also f(g(x))=x

so, what one function 'does' to x, the other 'undoes' it.



Thus, we have:

f(g(x))=x      and alos   f(g(x))= -g(x)+3, from the rule


thus : 

-g(x)+3=x

-g(x)=x-3

g(x)=-x+3


check: f(g(x))=f(-x+3)=-(-x+3)+3=x-3+3=x


Answer: the inverse of f is g, such that g(x)=-x+3

Math Help!!!!!!!

<h2><u>Answers and Explanation</u></h2>

<u>(a) Betty’s expression:</u>

Cost of guest = 10 × x + 10 × x + 10 × x

                    = 10x + 10x + 10x

cost of the venue = 80

Total cost =<em> 10x + 10x + 10x + 80</em>

<u>(b) Dawnie’s expression:</u>

Cost of the location  = $80

Number of guests = x + x + x

Cost of all guests = $10(x + x + x)

Total cost = <em> 10(x + x + x) + 80</em>

<u>(c) Joan’s expression:</u>

Cost of the location = 80

Cost of guest = 10 × x + 10 × x + 10 × x

                    = 10x + 10x + 10x

                    = x(10 + 10 + 10)     ⇒  After factoring out x.  

Total cost =<em> x(10 + 10 + 10) + 80</em>

3x-12=-4×+23<br>I need help with this pr​
Mrrafil [7]

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:

x=5

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−12=−4x+23

Step 1: Add 4x to both sides.

3x−12+4x=−4x+23+4x

7x−12=23

Step 2: Add 12 to both sides.

7x−12+12=23+12

7x=35

Step 3: Divide both sides by 7.

7x

7

=

35

7

x=5

Answer:

x=5
