Answer:

Step-by-step explanation:
Given the equation

A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so









Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.




Therefore,

Answer:
see explanation
Step-by-step explanation:
A polynomial in standard form begins with the term with the largest exponent and the remaining terms in descending order of exponents.
given
15
- 6x + 13x² - 1 ←
is largest exponent, hence
15
+ 13x² - 6x - 1 ← in standard form
Answer: what inside there?
Their signs are positive. if you multiple a positive by a positive, you get a positive. but if you multiple a negative by a negative, you get a positive. if you multiply two of the same sign numbers, the product is always positive.
