Answer:
f^-1(x) = x - 2
Step-by-step explanation:
To find the inverse of a function in terms of x and y, you would sway x and y in the function. We can rewrite f(x) = x + 2 as y = x + 2, since f(x) is basically y in a function. The inverse of y = x + 2 would be x = y + 2. Now, solve for y.
x = y + 2
-2 both sides.
x - 2 = y
y = x - 2
The inverse of y = x + 2 would be y = x - 2, so the inverse of f(x) = x + 2 would be f^-1(x) = x - 2 (f^-1(x) means the inverse of f(x)).
f^-1(x) = x - 2

Answer:
$22.67
Step-by-step explanation:
The school spends 635.85 dollars on passes for 43 students and 2 teachers, then the school spends
per person.
The school also spends 367.22 dollars on lunch for just the students, so the school spends
per person.
In total, a pass and lunch for each student was spent

Area of box : 18*18, which is 324
area of larger triangle : 18*16/2 which is 144
area of larger triangle : 8*16/2 which is 64
add them all to get 532
