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...

For any one-to-one function f(x)=yf(x)=y, a function f−1(x)f−1(x) is an inverse function of ff if f−1(y)=xf−1(y)=x. This can also be written as f−1(f(x))=xf−1(f(x))=x for all xx in the domain of ff. It also follows that f(f−1(x))=xf...
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...
inverse function for any one-to-one function f(x)f(x), the inverse is a function f−1(x)f−1(x) such that f−1(f(x))=xf−1(f(x))=x for all xx in the domain of ff; this also implies that f(f−1(x))=xf(f−1(x))=x for all xx in the domain of f−...
Luke has taught high school algebra and geometry, college calculus, and has a master's degree in education. There's a lot to know about inverse functions, so let's review what we've learned. A function's inverse is another function that does the exact opposite, and we use the negative...

Here's the algebra for finding that inverse, starting with the original function: y=−2x−5y=x−5−2 I multiply the denominator up to the left-hand side of the equation: y(x − 5) = −2 I take the y through the parentheses: xy − 5y = −2 I get the x-stuff...
