To find the inverse
replace f(x) with y
switch all x and y
solve for y
replace y with f⁻¹(x)
f(x)=x^2-9
y=x^2-9
x=y^2-9
x+9=y^2
sqrt both sides
replace
f⁻¹(x)=
that is the inverse

Answer:
y = -2
Step-by-step explanation:
Step 1: Combine like terms.
Step 2: Divide both sides by 9.
Step 3: Check if solution is correct.
Therefore, y = -2.
Answer:
2730
Step-by-step explanation:
We want to determine the greatest common divisor of the elements of the set
We apply the Fermat's little theorem which states that if p is a prime number, then for any integer a, the number aᵖ − a is an integer multiple of p.
Now, if p-1 divides 12.
Since the of 12 are 1,2,3,4, 6, 12, the corresponding primes are 2, 3, 5, 7, 13.
Therefore, the gcd of the elements in and
2*3*5*7*13=2730
Therefore, the gcd of the elements in set S is 2730.
