The function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
The graph of a function f(x) passes through the following points: (0,2), (1, 0), (-1,0)
Let
f(x) = ax² + bx + c
Plug x = 0, and y = 2
c = 2 ...(1)
Plug x = 1 and y = 0
a + b + c = 0 ..(2)
Plug x = -1 and y = 0
a - b + c = 0 ...(3)
After solving (1), (2), and (3)
a = -2
b = 0
c = 2
f(x) = -2x² + 2
Thus, the function is f(x) = -2x² + 2 if the function f(x) passes through the following points:(0,2), (1, 0), (-1,0)

we're going to verify every case
<u>case A)</u> For
substitute the value of x in the inequality
------> is true
therefore
The number is a solution
<u>case B)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case C)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case D)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
therefore
The answer Part 3) is the option A
