Find the inverse of f(x)=x^2-4x+3
Find the inverse of f(x)=x^2-4x+3-Sep 06, 15Your process is correct and your result is correct You could however stand to delete the line $2xy1=2xy$ from the proof I get that you were demonstrating what you did to both sides, but it doesn't make sense with the equals sign, and it's possible to go directly from $2xy3y=4x1$ to $3y1=4x2xy$ anywayGiven mathf(x) = x^3 6x^2 12x 8/math mathg(x) = f^{1}\left(x\right)/math ie the inverse of mathf(x)/math Required Find mathg'\left(x\right

Finite Math Find the Inverse Function f (x)= (x3)/x I am unable to solve this problemX = 2/ (y 3) x = 2/ (y 3) x (y 3) =2 xy 3x = 2 xy = 2 3x y = (2 3x)/x, x!= 0 Hopefully this helps!Apr 27, 15Thanks y = cos(x) 3 the inverse of this is x = cos(y) 3 solve for y and you have your inverse The cos function only has a range of 1,1, so the range of f(x) is 2,4 this means Trigonometry Having trouble with true/false questions in Trigonometry They read as follows True or False For a trigonometric function, y=f(x), then x=F^1
If you graph the given equation, f(x) = –x²Now this is a completely different function altogether, and it's defined for all x As x goes from (infty,infty) f (x) goes from (infty,infty) To find f inverse 1 you want 1 = cos (x) 3x you need some kind of root algroithm to solve this, but if you graph it you'll find x=0 then f (x)=1May 05, 18Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers Visit Stack Exchange
Divide f2, the coefficient of the x term, by 2 to get \frac{f}{2}1 Then add the square of \frac{f}{2}1 to both sides of the equation This step makes the left hand side of the equation a perfect squareHere is the procedure of finding of the inverse of a function f(x) Replace the function notation f(x) with y Swap x with y and vice versa From step 2, solve the equation for y Be careful with this step Finally, change y to f −1 (x) This is the inverse of the functionFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutor
