Answer:
(a) g^-1(x) = ±√(x -1)
(b) 0
(c) 17
Step-by-step explanation:
(a) The inverse is found by solving for y:
x = g(y)
x = y² +1
x -1 = y² . . . . . . subtract 1
y = ±√(x-1) . . . . take the square root
g^-1(x) = ±√(x -1) . . . . in functional form
Note: the inverse of g(x) is not a function, because it is double-valued.

(b) f(h(-2)) = f(-2+1) = f(-1) = f(-1+1)
f(h(-2)) = 0

(c) g(f(3)) = g(3+1) = g(4) = 4² +1
g(f(3)) = 17
Answer:
x≤16
Step-by-step explanation:
Because this is asking for men, we only look at males. we see that the first bar is barely under halfway between 15 and 20, meaning that it is 17. now the second bar is also barely under halfway between 5 and 10, so it is 7. now 17+7=24
Answer:
ABC
Step-by-step explanation:
Answer:
Breyana paid 88% of the dress's original price.
Step-by-step explanation:
We are given the following in the question:
Let x be the original price of dress.
The dress is on sale for 20%.
Price of dress after discount =
Breyana will also have to pay 10% sales tax on the discounted price of the dress.
Price of dress after discount =
Total cost of dress =
We have to calculate percentage of original price paid by Breyana
Thus, Breyana paid 88% of the dress's original price.
