Let y=f(x)=(3x+7)/(x-2) <br> find a rule for f^-1
Murrr4er [49]

Answer:

f^{-1}(x)=\frac{2x+7}{x-3}.

Step-by-step explanation:

The given function is f(x)=\frac{3x+7}{x-2},\:x\ne2.

We want to find a rule for f^{-1}(x).

Let y=\frac{3x+7}{x-2}.

Interchange x and y.

x=\frac{3y+7}{y-2}.

Solve for y.

x(y-2)=3y+7.

Expand

xy-2x=3y+7.

Group y-terms

xy-3y=7+2x.

Factor

(x-3)y=7+2x.

y=\frac{2x+7}{x-3}.

\therefore f^{-1}(x)=\frac{2x+7}{x-3},\:x\ne3.

Given f(x) = x − 7 and g(x) = x2 . Find g(f(4)). g(f(4)) =
Anastasy [175]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~

To solve this we will first find out what f(x) equals at the given point of 4, and than substitute that answer it for g(f(4))...

f(x) = x - 7

f(4) = 4 - 7 = -3

g(f(4)) = (x - 7)^2  >  -3^2 = 9

So...

The answer is: g(f(4)) = 9

Help me plz im stuck
viva [34]

Answer:

A) Fill the blanks, Fail, 0.15, Success, 244, 0.61

B) 240 times

Step by-step explanation:

A) Void , 96, 0.24

    Fail, 60, it should be 0.15 because 60/400

     Success, 400 - 96- 60 or 244 and the relative frequency is 0.61.

B)    

There is a total of 1000. If the relative frequency is 0.24, multiply 0.24 by 1000 to get the amount of times YOU would expect to be VOID.

Or in other words , 240 times

By proving it add all up

0.24 x 1000 + 0.76 x 1000 = 1000
