Brahmagupta's solution to a quadratic equation of the form ax? + bx = c involved only one solution. Which solution would he have found for the equation 3x2 + 4x = 6?
O x =
4(3)(6) + 42 - 4 - 2722-4 - V22 - 2
2 (3)
6

O x = 4(3)(4)
+62 - 6
2(3)
2/21-6-21-3

6
O x = 4(4)(6) + 32 - 3
2(4)
105 - 3
8
O x = 4(3)(6) – 42 +4 - 2/14+4
14 + 2

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
