Answer:

x=-4

Step-by-step explanation:

4(x+4)=0

multiply x and 4 by 4

4x+16=0

subtract 16 from both sides.

4x=-16

divide both sides by 4

x=-4

Graph the inverse of the function.
Ghella [55]

Answer:

The graph of the inverse function is the same that the graph of the original function

Step-by-step explanation:

step 1

Find the equation of the function in the graph

Let

f(x) ---> the function in the graph

we know that

Is a linear function

take the points (0,6) and (6,0)

<em>Find the slope of the linear function</em>

m=(0-6)/(6-0)\\m=-1

<em>Find the the equation of the linear function in slope intercept form</em>

f(x)=mx+b

we have

m=-1

b=6 ---> the y-intercept is given

substitute

f(x)=-x+6

step 2

Find the inverse of the function f(x)

Let

y=f(x)

y=-x+6

<em>Exchange the variables (x for y and y for x)</em>

x=-y+6

Isolate the variable y

y=-x+6

Let

f^{-1}(x)=y

f^{-1}(x)=-x+6

f^{-1}(x)=f(x)

In this problem the graph of the inverse function is the same that the graph of the original function
