An equation that defines y as a function of x is given. Rewrite the equation using function notation f(x).
-$$y - 3 x ^ { 2 } = 8 - x$$
A) $f ( x ) = 3 x ^ { 2 } + x + 8$
B) $f ( x ) = - 3 x ^ { 2 } + x - 8$
C) $f ( x ) = 3 x ^ { 2 } - x + 8$
D) $f ( x ) = - 3 x ^ { 2 } - x + 8$

Question

Quizplus · Accepted Answer

To express y as a function of x, solve for y: $y = 3x^2 - x + 8$. Thus, $f(x) = 3x^2 - x + 8$.
