write the answer in correct \[f ^{-1}(x)\]
OpenStudy (burb):
the equation is \[g(x)=\frac{ x-7 }{ -2 }\]
OpenStudy (supersmart1001):
hm ok this will take me a min
OpenStudy (supersmart1001):
The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5 or at least thats what i got
OpenStudy (burb):
\[3x^2 or 3x2\]

to find the inverse, you first equate the function to y
g(x)=y
so now
y=x-7/-2
now try to make x the subject of formula. for this the first and thing to do would be to take the -2 and and multiply it by y. now we have
-2y=x-7
now we'll simply bring the -7 to the other side and change the y back to x. we'll have
-2x+7 or 7-2x
get it?
