What is the inverse function for f(x)5x-20?

To find the inverse of a function, you have to switch y for x and then solve for y again. These are the steps: y = 5x - 20 x = 5y - 20 5y = x + 20 y = 0.2x + 4 or f(x)^-1 = 0.2x + 4


What is the inverse of f of x equals 5x plus 4?

No, f(x) is not the inverse of f(x).


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.


Is it possible for a fourth degree function to have an inverse that is a function?

In order for a fourth degree function to have an inverse function, its domain must be restricted. Otherwise the inverse function will not pass the vertical-line test.Ex.f(x) = x^4 (x>0), the original functionf-1(x) = x ^ (1/4), the inverse


What is the inverse of the function f(x) 4x?

if f(x) = 4x, then the inverse function g(x) = x/4


What is the difference between a reciprocal function and an inverse function?

A reciprocal function will flip the original function (reciprocal of 3/5 is 5/3). An inverse function will change the x's and y's of the original function (the inverse of x<4,y>8 is y<4, x>8). Whenever a function is reflected over the line y=x, the result is the inverse of that function. The y=x line starts at the origin (0,0) and has a positive slope of one. All an inverse does is flip the domain and range.


Is 5x plus 4y equals 0 a function?

Yes it is a function. 5x + 4y = 0 the same as: 5x = -4y You can also solve for either variable. x = - ( 4 / 5 ) y y = - ( 5 / 4 ) x


What is the inverse function for 4 over x?

1. its -4 over x


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 function is the inverse of a quadratic function?

If the quadratic function is f(x) = ax^2 + bx + c then its inverse isf'(x) = [-b + +/- sqrt{b^2 - 4*(c - x)}]/(2a)


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
