Answer:
I am attaching photo hold on
A represents a function because each of the input values {-5, -2, 2, 5} has one and only one output (y-) value associated with it.
The same could be said of B: Each of the four input values {4, 3, 9, 11} has one and only one output (y-) value associated with it.
Thus, in both cases the given relations are also functions.

I solve temp change like this(an am correct):
You remove the minus from the negative number and add both numbers and you have your answer.
56+44=100
Your answer is:100 degrees Fahrenheit.
Answer:
f^-1(x) = 4x^2 -3 . . . . x ≤ 0
Step-by-step explanation:
Interchange x and y, then solve for y.
x = -1/2√(y+3)
-2x = √(y +3)
4x^2 = y +3
4x^2 -3 = y
Note that the range of the function f(x) is f(x) ≤ 0, so this will be the domain of the inverse function. Then the inverse function is ...
f^-1(x) = 4x^2 -3 . . . . for x ≤ 0
___
The attached graph shows this inverse function is a reflection of the function across the line y=x, as it should be.
X + y = 22,102
.11x = .07y + 913.46 = x= (7/11)y + 8304.18
((7/11)y + 8304.18) + y = 22,102
(18/11)y = <span>13797.82
</span>
y= 13797.82/(18/11)
y=8432.00
8,432.00 dollars are invested at 7%
13,670.00 dollars are invested at 11%
Check
.07 x 8432= 590.24
.11 x 13,670 = 1503.70
1503.70 - 590.24 = 913.46
