Webb21 feb. 2024 · Prove that f(x) is a bijection. To prove that a function is a bijection, we have to prove that it’s an injection and a surjection. To prove that it’s an injection, we use this test: f(a) = f(b) = a = b (if this is true for the function then it’s an injection) In this case, we have. a 3 = b 3. So, since they’re both cubed, we have. a = b http://ramanujan.math.trinity.edu/rdaileda/teach/s20/m3326/lectures/bijections_handout.pdf
