Define the first injective function, f1: A B.

To write two injective functions from set A = \x,y,z\ to set B = \1,2,3,4\, we need to ensure that each element in A maps to a unique element in B. Step 1: Define the first injective function, f_1: A B. We can map the elements of A to distinct elements of B. f_1(x) = 1 f_1(y) = 2 f_1(z) = 3 This function is injective because each element in A maps to a different element in B. Step 2: Define the second injective function, f_2: A B. To make it different from f_1, we can change one or more of the mappings, ensuring it remains injective. f_2(x) = 1 f_2(y) = 2 f_2(z) = 4 This function is also injective because each element in A maps to a different element in B. The two injective functions are: f_1: A B defined as f_1(x) = 1, f_1(y) = 2, f_1(z) = 3. f_2: A B defined as f_2(x) = 1, f_2(y) = 2, f_2(z) = 4. These are just two examples; many other injective functions are possible. The two injective functions are: f_1 = \(x,1), (y,2), (z,3)\ f_2 = \(x,1), (y,2), (z,4)\ Send me the next one 📸
