What is the inverse of this function?
Answers
Answer:
[tex]f^{-1}(x)=4x^2-3[/tex]
Step-by-step explanation:
The Inverse of a Function
Given a function f(x), the inverse of f, called [tex]f^{-1}(x)[/tex] is a function that satisfies:
[tex]f(f^{-1}(x))=x[/tex]
The domain of f becomes the range of its inverse and vice-versa.
The procedure to find the inverse of the function is:
* Write the function as a two-variable equation:
* Solve the equation for x.
* Swap the variables
We are given the function:
[tex]\displaystyle f(x)=-\frac{1}{2}\sqrt{x+3}[/tex]
Defined in the interval x ≥ -3
Note f is always negative, thus its range is f(x) ≤ 0
Now we find the inverse. Call y=f(x):
[tex]\displaystyle y=-\frac{1}{2}\sqrt{x+3}[/tex]
Multiplying by 2:
[tex]\displaystyle 2y=-\sqrt{x+3}[/tex]
Squaring both sides:
[tex]\displaystyle 4y^2=x+3[/tex]
Subtracting 3:
[tex]\displaystyle 4y^2-3=x[/tex]
Swapping variables:
[tex]y=4x^2-3[/tex]
Thus:
[tex]\mathbf{f^{-1}(x)=4x^2-3}[/tex]
The domain of the inverse is the range of f, thus x is restricted to
x ≤ 0

2m-4 ≥ 10
Answers
Answer:
m = 7
Step-by-step explanation:
2m + -4 = 10
Reorder the terms:
-4 + 2m = 10
Solving
-4 + 2m = 10
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2m = 10 + 4
Combine like terms: -4 + 4 = 0
0 + 2m = 10 + 4
2m = 10 + 4
Combine like terms: 10 + 4 = 14
2m = 14
Divide each side by '2'.
m = 7
Simplifying
m = 7

Mixed number: [tex]3\frac{15}{100}[/tex]
Improper fraction: [tex]\frac{315}{100}[/tex]
Step-by-step explanation:
A mixed number is a number that contains an integer part and a fraction part.
An improper fraction is a fraction where the numerator is greater than the denominator.
[tex]3.15[/tex] can be written as [tex]\frac{315}{100}[/tex] in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.
The mixed number is [tex]3\frac{15}{100}[/tex] since [tex]100[/tex] goes into [tex]315[/tex] three full times and the remainder is [tex]15[/tex].
∴The mixed number is [tex]3\frac{15}{100}[/tex] and the improper fraction is [tex]\frac{315}{100}[/tex].

What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true.
Such values are called solution to that equation or inequality.
The Set of such values is called solution set to the considered equation or inequality.
The graph as shown in the task content includes the horizontal line; y = 2 and the line; y = x.
However, the area shaded in the graph coincides with the upper area of y = 2 with broken lines as boundary and the lower area of line; y = x with a solid boundary line.
Hence, The inequalities represented by the graph are; y < 2 and y >= x.
So option C is correct.

d. $57,609.18
e. $57,583.68
Answers
Answer:
Annual withdraw= $57,583.68
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $555,000
Interest rate (i)= 0.0825
Number of periods (n)= 20
To calculate the annual withdrawals, we need to use the following formula:
Annual withdraw= (PV*i) / [1 - (1+i)^(-n)]
Annual withdraw= (555,000*0.0825) / [1 - (1.0825^-20)]
Annual withdraw= $57,583.68
