If a quadratic function has x-intercepts at 2 = -

PolarNik [594]

Complete question is;

If a quadratic function has x-intercepts at x = -3 and x = -1, one possible equation of the function would be y = (x + 3)(x + 1), a graph that first

decreases until it reaches the vertex, (-3, -1), then increases (opening upward U shape).

So then, if a quadratic function has x-intercepts at x = -2 and x = 2

a. What is the equation of this quadratic function? Explain your reasoning

b. What is the vertex of the equation? Show your work and explain your reasoning.

Answer:

Quadratic equation is; y = x² - 4

Vertex: (0, -4)

Step-by-step explanation:

The x-intercepts are at x = -2 and x = 2. Thus, the equation is;

y = (x - (-2))(x - 2)

y = x² + 2x - 2x - 4

y = x² - 4

Now,the coordinates of the vertex will be (h, k)

Where;

h = -b/2a

k is the value of y at x = h

From y = x² - 4, h = 0

Thus, putting x = h = 0 in the quadratic equation, we have;

y = 0² - 4

y = -4

Thus,the coordinates of the vertex are; (0, -4)

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3

Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

$1 \frac{1}{2}$ ÷ $4 \frac{1}{2} * 1 \frac{1}{3}$ = $\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

$\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$ = $\frac{3}{2} *\frac{2}{9} *\frac{4}{3}$

Now we just multiply the fractions!

$\frac{3 * 2 * 4}{2 * 9 * 3}$ = $\frac{4}{9}$

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
