The graph of a quadratic function is called a parabola.
There are 3 forms of quadratic equations.
If A is positive, the parabola opens up or to the right.
If A is negative, it opens downwards or to the left.
All quadratic equations have a vertex, which is the turning point of the graph.
Quadratic graphs are symmetrical across the y-axis, which runs through the axis of symmetry. Formula: x= -b/2a
A quadratic function crosses the y-axis when x=0
The y-intercept always has an x-value of 0.
For a parabola, the y-intercept will be the point(don’t know this one sorry!)
A quadratic function crosses or touches the x-axis once, twice, or never.

Step-by-step explanation:

Example:

y=1x+4

To find x-intercept:

0=1x+4

Two 2 1/2 inch plastic strips and two 5 1/3 inch plastic strips are used to form a rectangle. What is the perimeter of the recta
svp [43]
In this question the given information's should be closely noted. The length and width of the perimeter are already given. Based on those information's the answer to the question can be easily deduced.
Length of the rectangle = 2 1/2 inch
                                       = 5/2 inch
Width of the rectangle = 5 1/3 inch
                                         = 16/3 inch
Then
Perimeter of a rectangle = 2 ( Length + Width)
                                        = 2 [(5/2) + (16/3)]
                                         = 2 [ (45 + 32)/6]
                                         = 2 * (77/6)
                                         = 77/3 inch
                                         = 25 2/3 inch
So the perimeter of the rectangle in question is 25 2/3 inch. I hope the procedure is clear to you.
