Answer :
Answer:
k = ±√3
Step-by-step explanation:
Given :
- f(x) = 3 - 2x²
- f(k) = -3
To find the value of k, we need to equate both the functions to find the value of x such that it is equal to the value of k.
- ⇒ 3 - 2x² = -3
- ⇒-2x² = -6
- ⇒ x² = 3
- ⇒ x = ±√3
We already set a relation before, which is :
- x = k
- Therefore, k = ±√3
