Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial that the highest exponent is "2", which is the exponent of the term
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.
Features of a Parabola
The equation of a parabola can be written as:
Answer:
f'(x) > 0 on and f'(x)<0 on
Step-by-step explanation:
1) To find and interval where any given function is increasing, the first derivative of its function must be greater than zero:
To find its decreasing interval :
2) Then let's find the critical point of this function:
2.2 Solving for x this equation, this will lead us to one critical point since x' is not defined for Real set, and x''≈0.37 for e≈2.72
3) Finally, check it out the critical point, i.e. f'(x) >0 and below f'(x)<0.
