(2)
Step-by-step explanation:
Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)
Thus,
=> -x³ - 9 = y
=> - y - 9 = x³
=> (-y - 9)^(1/3) = x
=> f(y) = x
Inverse is (-y-9)^(1/3)
Replacing the variable, inverse is (-x-9)^(1/3)

Point C is tangent to the circle and will be a right angle which is 90 degrees.
The three inside angles of a triangle need to equal 180.
X = 180-90-64 = 26
X = 26 degrees
