Answer:

Question 3:
For this case we must find the inverse of the following function:

To do this, we follow the steps below:
We change y for
:

We exchange variables:

We clear the value of the variable "y":

We change y for
:

Answer:

Answer:
y = -2x - 8 OR y + 8 = -2(x - 0)
Step-by-step explanation:
Slope-Intercept Form: y = mx +b
b + y-intercept
m = Slope
y = -2x +(-8)
Point-Slope Form: y- y1 = m(x - x1)
y - (-8) = -2(x - 0)
