Question

If f(a) = K, then which of the following must be true? f(K) = a f -1(K) = a f -1(a) = K

Answer 1

Answer:

Step-by-step explanation:

given that f(a) = K

we have the options of

f(K) = a

f ⁻¹ (K) = a

f ⁻¹ (a) = K

Where f ⁻¹ denotes an inverse function.

If f(a) = K, then its reciprocate, f ⁻¹ (K) = a

because it is essentially undoing the original equation
