The inverse function of the above function is f(x) = 2x - 8 and therefore the function at 4 would be equal to 0.
You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:
f(x) = 1/2x + 4 ----> Switch the x and f(x)
x = 1/2f(x) + 4 ---> subtract 4 from both sides
x - 4 = 1/2f(x) ----> multiply both sides by 2
f(x) = 2x - 8
This would be your inverse function. Now to find f-1(4) you would put 4 in for x in your new inverse function.
f(x) = 2x - 8
f(4) = 2(4) - 8
f(4) = 8 - 8
f(4) = 0
It is A. 60° because each triangle I 30° and they are two apart
Answer:
2 cups more was given to the flower with the most water because 5 cups - 3 cups = 2 cups.
Answer:
3x-3(6) = 3x-18
Step-by-step explanation:
Answer:
The diameter of the pizza = 14 in
Radius of the pizza = (14/2)in = 7in
Area of a whole pizza =
πr^2
=( 22/7 × 7^2)in^2
=( 22/7 × 49)in^2
154 in^2
Area of a half pie =( 1/2 × 154)in^2 = 77in^2
Area of one of 8 slices = (1/8 × 154)in^2 = 19.25in^2
Hope it helps
