Answer:

  f⁻¹(x) = √((3 -x)/3)

Step-by-step explanation:

A function gives you a y-value for each value of x.

  y = f(x)

__

An inverse function tells you the x value that produced a given y-value. It is the solution to the equation ...

  x = f(y)

So, we want to find y for ...

  x = -3y² +3

  x -3 = -3y² . . . . . . . . . . . subtract 3

  (x -3)/-3 = y² . . . . . . . . . divide by -3

  √((x -3)/-3) = y . . . . . . . take the square root.

The requirement for x > 0 in the original function means y > 0 for the inverse function. That is why we use the positive square root.

This can be simplified a little bit to remove the minus sign from the denominator.

  f⁻¹(x) = √((3 -x)/3)

__

The graph plots the function and its inverse. They are reflections of each other over the line y=x. (That's one way you can tell you have the correct inverse function.)

My question is in the attachment
Svetllana [295]

Answer:

x = 1

Step-by-step explanation:

\frac{4x-1}{2}+\frac{3x+4}{3}= \frac{23}{6}

\frac{3(4x-1)}{6}+\frac{2(3x+4)}{6}= \frac{23}{6}

\frac{12x-3+6x+8}{6}=\frac{23}{6}

18x + 5 = 23

18x = 23 - 5

18x = 18

x = 1

Therefore, x = 1 is the solution of the given expression.

What is tan C ?
MatroZZZ [7]

Answer:

\frac{1}{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC of the figure, the tangent of angle C is equal to divide the opposite side to angle C (side AB) by the adjacent side to angle C (side BC)

so

tan(C)=\frac{AB}{BC}

substitute the given values

tan(C)=\frac{11}{22}

simplify

tan(C)=\frac{1}{2}
