WebApparently, you plugged 3 into F and got 5 2. Then you took the reciprocal of that to get your answer. But the superscript − 1 doesn't me "multiplicative inverse", but "function inverse." Asking what F − 1 ( 3) means finding what value of a to plug into F ( x) to get 3. That is, solve F ( a) = 3. So you need to solve the equation 3 a − 1 2 = 3. WebNov 14, 2024 · Find f − 1 ( 2) and a formula for f − 1 ( x). Note that 2 × 3 = 1 ( mod 5). I've found that f − 1 ( 2) = 0 but I can't find the equation for the inverse of f ( x) and I don't know how their clue of "Note that 2 × 3 = 1 ( mod 5) " is relevant. Please help!
