Find the inverse Algebra

Mathematics
1 answer:
myrzilka [38]3 years ago
7 0

Step-by-step explanation:

a) k(x) = (x - 2)² - 4 → x = (y - 2)² - 4 → (y - 2)² = x + 4 → y - 2 = ±√( x + 4) → y = 2 ±√( x + 4) → k-¹(x) = 2 ±√( x + 4)

b) f(x) = ½(x + 2)² - 3 → x = ½(y + 2)² - 3 → ½(y + 2)² = x + 3 → (y + 2)² = 2x + 6 → y + 2 = ±√(2x + 6) → y = -2 ±√(2x + 6) → f-¹(x) = - 2 ±√(2x + 6)

If -3 is a lower bound for the real zeros of f(x), then -2 is also a lower bound.
vladimir1956 [14]

The statement is false, because -2 is larger than -3.

<h3>Is the statement true?</h3>

We know that -3 is a lower bound for the real zeros of f(x).

So, if we define k as the smallest real zero of f(x), we have:

-3 < k.

Then we can take, for example, k = -2.5

That is an allowed value for the real zero.

In that case, -2 is not a lower bound, because is false that:

-2 < k = -2.5

Then if -3 is a lower bound for the real zeros of f(x), we can't assume that -2 is also a lower bound (because -2 is larger than -3).

If you want to learn more about lower bounds:
