Sagot :
Answer:
C) The graph opens down and the vertex is a maximum.
Step-by-step explanation:
Just took the quiz on K12, good luck! :)
Option (C) will be the correct option.
Properties of a quadratic equation:
- If a quadratic function has been given as,
f(x) = ax² + bx + c
Vertex of the parabola is represented by [tex][-\frac{b}{2a}, f(\frac{b}{2a})][/tex]
And the sign of the leading coefficient decides the opening of the
parabola.
For positive sign of 'a' → Parabola will open upwards
For negative sign of 'a' → Parabola opens downwards
Quadratic function given in the question is,
f(x) = -4x²+ 6x - 7
Leading coefficient → (-4)
Negative sign represents the opening of the parabola downwards.
And the vertex will be a maximum.
Therefore, Option (C) will be the correct option.
