The correct answer is: [C]: " c(x) = –8x²<span> + 3x – 5 " .
_________________________________________________________
The quadratic function takes the form of:
_________________________________________________________
" f(x) = ax</span>² + bx + c " .

Answer choice: [C]: " c(x) = –8x² + 3x – 5 " ;
is the only answer choice provided that takes that form of the quadratic function:
" f(x) = ax² + bx + c " :
in which: " a = -8 " ; " b = 3 " ; " c = -5 " .

Answer:
F and H
Step-by-step explanation:
From the image attached, the location of the points are E = -9, F = -6, G = -2, H = 6, I = 8. The law of additive inverse states that for a number a, its additive inverse is a number that when added to a equals to zero. This number is usually opposite in sign to a and of the same magnitude i.e -a. The law is given as:
a + (-a) = 0
From the points, F is the additive inverse of H, hence:
F + H = 0
6 + (-6) = 6 - 6 = 0
Hence the two points are F ad H
3 x 2.7 is the same as 3 x 3 x 0.9 = 9 x 0.9 = 8.1
