Answer:

Step-by-step explanation:

To find the inverse of this function, temporarily the f(x) with a y (or whatever else you want) and then solve for the x.

Now, you can swap the variables again and write the function.

Answer:
-x
Step-by-step explanation:
8x - 9x
Factor out an x
x(8-9)
x (-1)
-x
Answer:
m = -4
b = -12
Step-by-step explanation:
First, identify the slope-intercept form:
y = mx + b
y = -4x - 12
Whereas m = slope and b = y-intercept.
Slope is the steepness of the line.
The y-intercept is where the line intersects the y axis.
