The standard form of the quadratic function in this problem is given as follows:
y = -0.25(x² - 4).
<h3>How to define the quadratic function?</h3>
The standard definition of a quadratic function is given as follows:
y = ax² + bx + c.
Considering it's roots x' and x'', the definition are given as follows:
y = a(x - x')(x - x'')
In which a is the leading coefficient.
From the table given by the image at the end of the answer, the roots are given as follows:
x' = -2, x'' = 2.
(as they are the values of x for which y = 0).
Then:
y = a(x + 2)(x - 2)
y = a(x² - 4).
When x = 0, y = 1, hence the leading coefficient is given as follows:
1 = -4a
a = -1/4.
a = -0.25.
Hence the equation is of:
y = -0.25(x² - 4).

Answer:
If it is in y=mx+b form, you use your slope.
Step-by-step explanation:
In the equation y=5x+0, you would graph a point at (0,0). Next you would go up five and to the right one b/c 5 is really 5/1. The top number tells up or down and the bottom number tells you left or right. Left/down is negative and right/up is positive. In the equation y=4x-3, you would plot a point at (0,-3). Then go up four and right one. In the equation y=1/5 x+4, you would plot a point at (0,4). Then go up one and to the right 5.
