What is the equation of the graph below?

IgorC [24]

ANSWER

$f(x) = (x + 3)^{2} - 1$

EXPLANATION

The vertex of the graph is at

$(-3,-1)$

The equation of the graph in vertex form is given by the formula,

$f(x) = a{(x - h)}^{2} + k$

The above graph has a minimum point, hence
$a > \: 0$

When we put these values into the equation we obtain,

$f(x) = a(x - - 3)^{2} + - 1$

This implies that,

$f(x) = a(x + 3)^{2} - 1$

The point (-2,0) lies on the line.

$a( - 2 + 3)^{2} - 1 = 0$

$a = 1$

$f(x) = (x + 3)^{2} - 1$

The correct answer is D.

1/4 +1/3 divided by4/5

ad-work [718]

Answer:

2/3

Step-by-step explanation:

Do 1/3 divided by 4/5 first.

So we are going to flip 4/5 to 5/4. The equation is now:

1/4+1/3 times 5/4

Now we are going to do the multiplication since multiply and division is before adding and subtraction.

1/3 times 5/4 = 5/12

Now we have to add 1/4+5/12

With adding ( and subtracting) we have to find the common denominator which is 12

So now we have 3/12 + 5/12 = 8/12 which reduces to 2/3
