What is the inverse function of y equals 2x minus 4?

To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.


What is the function of f(x)-x2 plus 2x-3 when x-3?

The inverse for f(x) = 4x + 8 isg(x) = x/4 - 2


How do you rewrite as a function of x using function notation for 2x plus 3y equals 4?

If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.


Is y equals 2x plus 4 a function?

Yes.


What can you say about the end behavior of the function f(x)- In (2x) plus 4?

You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.


How do you write the inverse function of -4?

Well, it would be hard to write an inverse function of -4, since -4 is not a function in the first place.


What is 2x-1 plus 2x-1 plus 2x-1 plus 2x-1?

8x-4


What is the answer to 2x plus 5 plus x2x-1 plus 2x plus 4?

x equals 4


Which function is the inverse function of y 5x - 4?

1


2x plus 4 plus 7x-4?

2x+4+7x-4 is the same as 9x


What is the answer to -2x to the 4 plus 16 plus 2x to the 4 plus 9-3x to the 5?

-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.


What is the discontinuity and zero of the function fx the quantity of 2 x squared plus 5 x minus 12 all over x plus 4?

f(x) = (2x^2 + 5x - 12)/(x + 4) as given, is not defined when the denominator is 0 ie when x + 4 = 0 or x = -4. However, 2x^2 + 5x - 12 = (x + 4)*(2x - 3) so that the function can be simplified to (x + 4)*(2x - 3)/(x + 4) = 2x - 3 This has a zero when 2x - 3 = 0 ie 2x = 3 or x = 1.5
