Ques: Find the inverse of the function y = 4x - 7/4.Choices:A. y = 4x + 3 B. y = 4/4x + 7 C. y = 4x +7/4 D. y = x + 7 Correct Answer: CSolution:Step 1: y = 4x - 7/4. Step 2: Interchange x and y and find y in terms of x. Step 3: x = 4y - ...
f( f-1(11) ) = 11 "f of f inverse of 11 equals 11"Solve Using AlgebraWe can work out the inverse using Algebra. Put "y" for "f(x)" and solve for x:The function: f(x) = 2x+3 Put "y" for "f(x)": y = 2x+3 Subtract 3 from both sides: y-3 = 2x Divide both sid...

f−1(x)=5x−12x+1 … x≠−12How to Find Inverse Functions Using AlgebraWe can replace f(x) with y and solve the algebraic expression in terms of x. Consider an example.Function: f(x)=5x−9Replace the f(x) with y: y=5x−9...
If some physical machines can run in two directions, we might ask whether some of the function “machines” we have been studying can also run backwards. Figure 1 provides a visual representation of this question. In this section, we will consider the reverse nature of functions. ...

Interchange the x with y and the y with x in the function y = ax + b to obtain x = ay + b. Here solve the expression x = ay + b for y. And we obtain y = (x - b/a Finlly replace y = f-1(x), and we have f-1(x) = (x - b)/a. ...
Often we can find an inverse function or partial inverse function by solving equations. For example, if y = x2 + 1, then x2 = y − 1 and x=y−1 when y≥ 1 and x≥ 0. The negative square root also satisfies the original equation, x=−y−1. The algebra of inverse funct...
