Standard form of a parabola is (y-k) =a(x-h)² or y= a(x-h)² +k

The vertex of a parabola is v(h,k).

We have already h & k ( given) ==>v(-5, -2), we still have to calculate "a", the coefficient of the squared expression:
1st info: replace h & k by their respective values: y=a(x+5)² -2
2nd info: when x= -4, y= 2. Replace y & x  in the above equation so that to find a:  2 =a(-4 + 5)² -2==> 2=a(1)² - 2==> a=4 coef. of sqaared expression

No, they forgot to switch variable labels after solving for the independent variable...

y=-8x+4

y-4=-8x

(y-4)/-8=x 

Now that you have solved for the independent variable x, you switch the variable labels...

y=(x-4)/-8

f^-1(x)=(x-4)/-8     which should really be rewritten as:

f^-1(x)=(4-x)/8  :P
