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: a= 3r^6-b b=0
Step-by-step explanation:
take the root of both sides and solve
1a+18=7a
18=7a-1a
18=6a
6a=18
a=18/6
a=3
