Answer:
-11.
Step-by-step explanation:
f(x) = √(3 - 2x), x ≤ 3/2
let y = √(3 - 2x)
y^2 = 3 - 2x
2x = 3 - y^2
x = (3 - y^2)/2
So f-1(x) = (3 - x^2)/2
f-1(x) = (3 - 5^2) / 2 = -11.
Answer: A,C,D

Answer:
1 I don't know if those are questions but try if they are try the first one a
Answer:
d) not proportional
Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
The answer would to this question would be 16/40 or 40%.
