Can a quadratic have an inverse

WebWe can write this as: sin 2πœƒ = 2/3. To solve for πœƒ, we must first take the arcsine or inverse sine of both sides. The arcsine function is the inverse of the sine function: 2πœƒ = arcsin (2/3) πœƒ = (1/2)arcsin (2/3) This is just one practical example of using an inverse function. There are many more. 2 comments. WebFinding inverse of a quadratic function : Let f (x) be a quadratic function. Step 1 : Replace f (x) by y and interchange the variables x and y. Step 2 : Solve for y and replace y by f …
