Given f(x) = -x^2 - 2x + 4, find each of the following, Symmetric point:
Minimum of f:
Maximum of f:
Is f a one-to-one
Does f have an inverse?
Increasing on
Decreasing on

Symmetric point: x = 1.

Minimum of f: None; approaches -∞.

Maximum of f: y = 1.

Is f a one-to-one: No, it fails the horizontal line test and is not injective.

Increasing from: -∞ to 1.

Decreasing from: 1 to ∞.

Step-by-step explanation:

Let me make sure.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
