The function of f(x) = 3x + 2 has a domain of -3 &lt; x &lt; 5. What is the domain of f-1(x)?
Flura [38]
<h3>Answer:    -7 < x < 17</h3>

====================================================

Explanation:

Plug in the lower bound of the domain, which is x = -3

f(x) = 3x+2

f(-3) = 3(-3)+2

f(-3) = -9+2

f(-3) = -7

If x = -3, then the output is y = -7. Since f(x) is an increasing function (due to the positive slope), we know that y = -7 is the lower bound of the range.

If you plugged in x = 5, you should find that f(5) = 17 making this the upper bound of the range.

The range of f(x) is -7 < y < 17

Recall that the domain and range swap places when going from the original function f(x) to the inverse f^{-1}(x)

This swap happens because how x and y change places when determining the inverse itself. In other words, you go from y = 3x+2 to x = 3y+2. Solving for y gets us y = (x-2)/3 which is the inverse.

-----------------------

In short, we found the range of f(x) is -7 < y < 17.

That means the domain of the inverse is -7 < x < 17 since the domain and range swap roles when going from original to inverse.

Is 2000 centimeters equals blank m
ella [17]
Nooooow this is the story all about how my life got flipped turned upsidedown and id like to take a minute so sit right there and ill tell you how i became the prince of a town called Bel Air.

In west Philadelphia born and raised on the playground is where i spent most of my days. chillin out maxin relaxin all cool and all shootin some b-ball outside of the school

when a couple of guys, they were up to no good, started making trouble in my neighborhood. i got in one little fight and my mom got scared she said "youre moving with your auntie and uncle in bel air"

i begged and pleaded with her day after day, but she packed my suit case and sent me on my way. she gave me a kiss and then gave me my ticket i put my walkman on and said "i might as well kick it."

first class yo, this is bad drinkin orange juice outta champagne glass is this what the people of bel air be livin like? hmmm this might be alright. but wait i hear theyre prissy, bourgeois, all that. is this the type of that they just send this cool cat?

i dont think so, ill see when im there. i hope theyre prepared for the prince of bel air. well the plane landed and when i came out there was a dude who looked like a cop standing there with my name. i aint trying to get arrested yet i just got here i sprang with the quickness like lightning, disappeared.

i whistled for a cab and when it came near the license plate said fresh and it had dice in the mirror. if anything i could say that this cab was rare. but i thought "nah forget it- yo homes to bel air!"

i pulled up to a house about 7 or 8 and i yelled to the cabbie "yo homes smell ya later!" i looked up at my kingdom, i was finally there. to sit on my throne as the prince of bel air.

5 + {2[(48 – 40) ÷ 4 + (2 x 5)]}
Black_prince [1.1K]

Answer:

29.

Step-by-step explanation:

The given expression is

5+2[(48-40)\div 4+(2\times 5)]

BODMAS = Bracket, Of, Division, Multiplication, Addition, and Subtraction.

Using BODMAS, we get

5+2[(8)\div 4+(10)]         (Brackets)

5+2[2+10]                  (Division)

5+2[12]               (Brackets)

5+24                 (Multiplication)

29           (Addition)

Therefore, the value of given expression is 29.
