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

Question

johnweldon1993 · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

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

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