The coordinates of the inverse function f⁻¹(x) will be swapped of the coordinates of the function f(x).
The complete question is attached below.
<h3>What is inverse of a function?</h3>
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
If the coordinates of the function f(x) are given.
Then the coordinates of the inverse function f⁻¹(x) will be swapped of the coordinates of the function f(x).
f(x) f⁻¹(x)
(33, 40) (40, 33)
(-19, -15) (-15, -19)
(-28, 47) (47, -28)
(-15, -34) (-34, -15)
(50, 0) (0, 50)

Answer:
390 cm squared
Step-by-step explanation:
15 x 20 = 300
1/2 x 15 x 12 = 90
90 + 300 = 390
Answer:
b. 11
Step-by-step explanation:
You'll have two equations in this system. Let G represent George's marbles and M represent Miguel's marbles.
1. G+3=2M (George's marbles plus 3 equals twice of Miguel's)
2. G-4=M (George's marbles minus 4 equals Miguel's marbles)
We have an explicit M value, so we can use the substitution method. Substitute the second equation into the first for M: G+3=2(G-4).
After some algebra, you'll get G=11. George has 11 marbles.
