Q:
Which function is a quadratic function?a(x) = –2x3 + 2x – 6b(x) = 5x3 + 8x2 + 3c(x) = –8x2 + 3x – 5d(x) = 6x4 + 2x – 3
Accepted Solution
A:
The correct answer is: [C]: " c(x) = –8x² + 3x – 5 " .
_________________________________________________________
The quadratic function takes the form of:
_________________________________________________________
" f(x) = ax² + 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 " .
