Answer:
Step-by-step explanation:
Answer with explanation:
Suppose, y=√x ,is a polynomial function.Here Domain =[0,∞)
→ y²=x
Range =(-∞,∞)
To find the inverse of the given function,replace x by y, and y by x in the original function.
So, x=√y, is the equation of inverse function.
if a point (x,y) lies on original function, then point (y,x) lies on the inverse function.
The graphed function given below passes through points
(1,0),(0,-1),(-2,-9),(2,7),and (-1,-2).
So, inverse function of the above function will pass through
(0,1),(-1,0),(-9,-2),(7,2),and (-2,-1).

Answer:
he can expect to lose 0.5$
Step-by-step explanation:
To solve this problem we must calculate the expected value of the game.
If x is a discrete random variable that represents the gain obtained when rolling a dice, then the expected value E is:
When throwing a dice the possible values are:
x: 1→ -$9; 2→ $4; 3→ -$9; 4→ $8; 5→ -$9; 6→ $12
The probability of obtaining any of these numbers is:
The gain when obtaining an even number is twice the number.
The loss to get an odd number is $ 9
So the expected gain is:
