Which is the graph of the function f(x) = x2 + 2x + 3?

Refer the graph attached.

Step-by-step explanation:

Given : Equation  

To find : The graph of the given equation?

Solution :  

Let,  

First we find the points which satisfy the equation and then joining those points give you the graph.

Points are

x      y

-3   6

-2   3

-1    2

0   3

1    6

Now, We plot these points.

The graph is the parabola with vertex (-1,2).

Refer the attached graph below.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
