5 0

Inverse of y=9-x²; you just replace x by y and y by x: x=9-y².

And the value of y: y² = 9-x and y =√(9 - x) [this is the inverse function]

f⁻¹(x) = √(9-x): CONDITION : (9-x) >=0, that means x< or = 9

Answer as per your problem:

The inverse of the function y = 9 - x 2, for all values x ≥ 3, is _____y =√(9 - x), where x can take values _____x<=9.

Which class has 28% 28% boys? Clear Check Class A: 3 3 out of 30 30 Class B: 28 28 out of 40 40 Class C: 1 1 out of 28 28 Class

konstantin123 [22]

Class A: 3 out of 30 = 3 / 30 = 0.1 = 10%

Class B: 28 out of 40 = 28 /40 = 0.7 = 70%

Class C: 11 out of 28 = 11 / 28 = 0.39 = 39%

Class D: 14 out of 50 = 14 / 50 = 0.28 = 28%
