In a pack of 52 cards, there are 3 square numbers - 1, 4, and 9.
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9
It is a Rectangle because a Rectangle has 4 sides.
Answer: Your question options are not legible but the inverse of the function is f-1(x) = (x + 2) / 2
Step-by-step explanation:
y = 2x + 2
Make x the subject of formula:
2x = y - 2
x = (y - 2) / 2
Now substitute y for x:
(x - 2) / 2
Y = (x - 2) / 2 is the inverse equation of the above graph.
