Identify the vertex, the axis of symmetry and the y intercept of the parabola below.please.
2 answers:
The vertex is where the parabola changes directions, or in simpler terms, at the parabolas lowest point. Unless the parabola is upside down, then the vertex is where the highest point is.
The acid of symmetry is the line where the parabola can be divided evenly. This is almost always where the vertex is, except it continues on.
The y-intercept is where the parabola intersects with the y-axis.

Answer:
25%
Step-by-step explanation:
Let the original price of A pair of skis be $100
discount given on A pair of skis = 20% on original price
discount value of A pair of skis in $ = 20% * $100
= (20 * 100)/100 = $20
discounted price of A pair of skis = original price - discount = 100 -20 = $80
in order to increase discounted price to original price of $100
there must be increase of $20 to discounted price which is $80
percentage increase on discounted price to return to the original price =
therefore 25% must be increase on discounted price to return to the original price
