Question

what is the inverse of y = 3x² - 11x - 4

Answer 1

switch all the x's and y's
y = 3x² - 11x - 4
becomes
x = 3y² - 11y - 4

now solve for y again

Answer 2

what would you do after \[x+4=3y ^{2}+11y\]

Answer 3

I meant to say x+4=3y^2-11y

Answer 4

from: x = 3y² - 11y - 4
x+4 = 3y² - 11y - 4
x+4 = y ( 3y - 11)
\[y=\frac{x+4}{3y-11}\]

Answer 5

the inverse of y=mx+c = y ^ -1 (that is inverse, swaping x n y) therefore it would be x=my+c, solve for x therefore 1. x - c = my 2. (x - c) / m = y, hope this helps

Answer 6

thanks

Answer 7

The inverse of a squared expression is going to be an expression involving a square root.
