The function f is defined for all real numbers x by f (x) = ax^2 + bx + c, where a , b , and c are constants and a is negative. In the xy-plane, the x-coordinate of the vertex of the parabola y = f (x) is −1. If t is a number for which f (t) > f (0), which of the following must be true?

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

true !

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
