X + 3 = 0 is not a function because it is a vertical line.
A vertical line has undefined slope because all points the line have the same x-coordinate.
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
Remember that a function can only take on one output for each input. Since a vertical line has the same x-coordinates for all values of y-coordinates, then it means that it is not a function.

Answer:
option B and option D
0 and 2
Step-by-step explanation:
Given in the question two functions
f(x) = x² - 4x + 3
g(x) = -x² + 3
f(x) = g(x)
x² - 4x + 3 = - x² + 3
Rearrange the like terms, x terms to the left and constant term to the right.
x²+ x² - 4x = 3 - 3
2x² - 4x = 0
Divide by two
2x²/2 - 4x/2 = 0/2
x² - 2x = 0
Take x as a common term
x(x-2) = 0
so
x = 0
or
(x-2) = 0
x = 2

<span>the ordered pairs given represent the input (x) and output (y) values from the given equation.
</span><span>points are (0, 10), (1, 5), and (2, 2.5)
</span><span>
f(x)=10(0.5)x
y=10(0.5)*(0)=0
y=10(0.5)*1=5
y=10(0.5)*2=10
means every time u give input increase by one the output is also increasing by 5 so answer is 5</span>
