Answer:
y =
y = -
Step-by-step explanation:
To find the inverse function, swap
x
x
and
y
y
, and solve the resulting equation for
x
x
.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables:
y=
x
2
−4
y=x2−4
becomes
x=
y
2
−4
x=y2−4
.
Now, solve the equation
x=
y
2
−4
x=y2−4
for
y
y
.
y=
x+4
