Answer:
(40-y)^3
Step-by-step explanation:
Make the unknown y
(40-y)^3
Answer:
28°F
Step-by-step explanation:
We can find the change in temperature by subtracting 44 from 72:
72 - 44 = 28
So, the change in temperature was 28°F
First find the value of "b" by substituting the co ordinates.
then you get as b=8.
next prove that right hand side is equal to the left hand side.
Answer:
a. 
b. 
c. 
Step-by-step explanation:
In a, the -1 means inverse of f(x). To find the inverse, you rewrite the equation in terms of x and y. You replace the x with y and y with x. Then you solve for y.






In b, all you have to do is plug in -9 into f(x).


In c, you plug in -9 into inverse function f.
