If i gave you 3 random points on a graph and i asked you to develop an exponential equation that would work for those 3 points, could you find its equation? I guarantee NONE of y'all could develop one and as a high school student, i figured out how to find its exponent, multiplier, and constant. I dare you to accept the challenge and prove me wrong ;) Develop en EXPONENTIAL EQUATION FOR THE POINTS: (4,1)  (11,11)  (13,121) REMEMBER AN EXPONENTIAL EQUATION LOL AND MY IQ IS 178

EQUATION IS((3^n )+ n,   11^(n-1)

x coordinate will be given by  (3^n )+ n

y coordinate will be given by  11^(n-1)

hey man thank you for actually taking the time to look at my question. Before you ask me to pay you anything I posted this question to see if any of y'all intellectuals could answer this question successfully. I did not ask you for a relationship in regards of "n". I gave you 3 points and asked you to find its exponential equation, giving me a defined exponent, multiplier, and constant. Since i gave you 3 given points, you can simplify the answers with true numerical answers. If i want to find the intercepts all i do is plug in "0" in the equation to find the y intercept and set the equation = to 0 for the x intercept. I do not need any help as i am here because i am bored out of my brains wanting beef with the smartest instructor on this site who would be more interested than what ends up in his bank account. I have a graphing notebook with me with the answers calculated. This is stuff i made up for my own creativity. This is what they didn't teach you in school even though they SHOULD HAVE. The equation should look something like y= (m(x-a)^n)+b  I made up the variables but it shouldn't matter because what ISN'T made up is the 3 points i gave you along with their exponential equation.

got you

formulating the three equations

eq 1

1= m(4-a) + b

b= 1- 4m  +ma

eq 2

11= m (11-a)^2  + b

eq 3

121 = m(13- a)^3 + b

Always assuming your customers are clueless because you want money... I remain correct, Yet again. You aint gonna prove me wrong bud and I KNOW you wont and thats engraved in stone.

wait sorry i thought you abandoned me lol

no no no no no. no. no. You are misunderstanding the puzzle to a severe degree. There is Only One Equation I want you to give me. There is not 3 equations. There is only One. I gave you 3 Points. I give you 3 Points because it fully constrains all possibilities as i ask you to give me a working exponential equation. When You give me the equation I want you to tell me the exponent, multiplier, and constant along with where the equation translates parallel to the x axis (x - number). Give me true blue numbers. I do not want you to give me m or b or n or any other variable. I promise you that this is out of sheer boredom man I'm not trying to get free answers from anywhere. The equation should look something like y= (multiplier(x- number)^exponent)+ constant. Again: Find the exponent, multiplier, constant. No Variables. I want TRUE BLUE NUMBERS LIKE 1,2,3, 4.67, 6,45, ETC. FOR EXAMPLE

Im not lying trust me. Hint: the exponent is between 8 and 14. the multiplier is a very small number. Give the answer to 3 significant figures so i know you got the numbers with accuracy. I did use a graphing calculator for the logBASE function too so you need one too or anything with a log function.

Ill give you the answer after your next response if you dont give me what i want to prove i am legit.

Oct 23rd, 2015

That's it. My patience is gone. Here is the answer: y=(.000000044053(x-4)^9.88764)+1 AND THATS ALL YOU NEEDED TO DO :D

Hope you learned something Mr. Tutor!

Oct 23rd, 2015

Thats actually correct. I was still working on it
