You have to searh the x values that make f(x) = 0

Factoring this equation is very difficult.

You can divide by x+3 and you will find that the equation can be factored as

(x+3)(x-4)^2

That means that x = -3 and x = 4 make f(x) = 0

Then the points are (-3,0) and (4,0).

Does the quadratic have a maximum or minimum

STALIN [3.7K]

Answer:

B)max/ opens down

Step-by-step explanation:

Parabola equation:

The equation of a parabola has the following format:

$y = ax^2 + bx + c$

If $a > 0$ , that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.

If $a < 0$ , that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.

In this question:

$y = -x^2 - 2x + 3$

From the graph, we already see that it opens down and has a max, and analitically, since $a = -1 < 0$ , this is confirmed. The correct answer is given by option b.
