Question

Given the equation
with solutions of
and
, which of the followingidentifies the general shape of its associated graph?
(1 point)
y = 3x2 − 24x + 48 x = 4 x = 4
The graph opens upward.
The vertex is to the left of the y-axis.
The entire graph lies above the x-axis.
The graph opens downward.

Answer 1

y = 3x^2 − 24x + 48 = 3(x − 4)^2, so the parabola has a double root at x = 4 and opens upward (coefficient 3 > 0).

Correct choice: The graph opens upward.
