Webleft parenthesis, x, plus, 5, right parenthesis, left parenthesis, x, minus, 4, right parenthesis. Solve ... Combine -4x and 5x to get x. x^{2}-4x+5x-20 . Apply the distributive property by multiplying each term of x+5 by each term of x-4. x^{2}+x-20 . Combine -4x and 5x to get x. WebWrite f (x) = x−5 f ( x) = x - 5 as an equation. y = x− 5 y = x - 5. Interchange the variables. x = y− 5 x = y - 5. Solve for y y. Tap for more steps... y = x+ 5 y = x + 5. Replace y y with f −1(x) f - 1 ( x) to show the final answer. f −1(x) = x+5 f - 1 ( x) = x + 5. townplace westport ma
