Determine the inverse of f x 4x + 12
WebSummary. The inverse function is a function which outputs the number you should input in the original function to get the desired outcome. So if f (x) = y then f -1 (y) = x. The inverse can be determined by writing y = f (x) and then rewrite such that you get x = g (y). Then g is the inverse of f. WebOr another way to write it is we could say that f inverse of y is equal to negative y plus 4. So this is the inverse function right here, and we've written it as a function of y, but we can just rename the y as x so it's a function of x. So let's do that. So if we just rename this y as x, we get f inverse of x is equal to the negative x plus 4.

WebMay 12, 2024 · Explanation: To find the inverse, we swap the x and y values. The original equation is f (x) = 4 x, meaning that the inverse would be x = 4 f (x). If you want it with f (x) by itself, first multiply f (x) on both sides of the equation: x ⋅ f (x) = 4 f (x) ⋅ (f (x)) x(f (x)) = 4. Divide both sides by x: x(f (x)) x = 4 x. Therefore, WebAn inverse function reverses the operation done by a particular function. In other words, the inverse function undoes the action of the other function. Given, f (x) = 4x - 12. First replace f (x) with y. y = 4x - 12. Next replace x with y and y with x. x = 4y - …

WebOct 19, 2024 · Steps. 1. Make sure your function is one-to-one. Only one-to-one functions have inverses. [1] A function is one-to-one if it passes the vertical line test and the horizontal line test. Draw a … WebFor example, let's say you complete the square on a quadratic and get: (x + 8)^2 = 121. When you take the square root of both sides you end up with: x + 8 = +/-11. Note that the square root of (x + 8)^2 is just x + 8, but that it is EQUAL to positive 11 or negative 11; this equality is explicitly stating that the square root of (x + 8)^2 can ...

WebJun 13, 2024 · y = 4x-12. To find the inverse of the function, we will make x the subject of the formula to have; y+12 = 4x. Dividing both sides by 4 gives; y+12/4 = x. x = y/4+12/4. x = y/4+3. The value of x gotten will be the inverse of the given function by replacing variable y in the function with x i.e. f^-1(x) = x/4+3 bitesize year 3 rocksWebYes, the inverse function can be the same as the original function. If the original function is symmetric about the line y = x, then the inverse will match the original function, down to the domains and ranges.
