Hello :
f'(7) = the slope of the tangent line : let A(7,4) B(0,3)<span>
<span>the slope is : (YB - YA)/(XB -XA)= (3-4)/(0-7) = -1/-7 = 1/7=f'(7)
the equation of the tangent line is :
y-3 = 1/7 (x-0)
y = (1/7)x+3
the line tangent and the graph of : f </span></span><span>passes through the point A(7, 4)
x= 7 y=4 so : f(7) =4</span>

Step-by-step explanation:
2×12=24 7×3=21 I started from 2×2 towards 2×12 when I got the answer and I started 7×1 towards 7×3
Answer:
The inverse of f(x) is 
Step-by-step explanation:
To find the inverse of the function
, perform the following steps:
1) do

2) Solve the equation for the variable x.


3) exchange the variable x with the variable y
----> 
4) Change the variable y by 
Finally the inverse function is:

The common minimum of those three numbers is 120.
