Find the inverse of a cubic function EXAMPLE 5 Find the inverse of a cubic function f (x) = 2x3 + 1 Write original function. y = 2x3 + 1 Replace f (x) with y. x = 2y3 + 1 Switch x and y. x – 1 = 2y3 Subtract 1 from each side. x – 1 2 = y3 Divide each side...
How do you find the inverse of a function? The steps for finding the inverse of a function, where they've given you a formula for the function, are these: Replace "f(x)" with y. Try to solve the equation for x=. Swap the x's and the y. Replace y with "f−1(x)" MathHel...
The syntax for using the inv() function is: B =inv(A); where A is the input square matrix and B is the output matrix, which is the inverse of A. Parameters The inv() function takes a single parameter: A:This is the input square matrix for which you want to calculate the inverse...
