Answer:

The solution of the equation graphically are (-3,0) and (4,-7).                        

Step-by-step explanation:

Given : Equation -x-3 = x^2 -2x- 15

To find : Solve the equation using graph?

Solution :

Let y=-x-3 be the equation (1)

y= x^2 -2x- 15 be the equation (2)

If we plot the equation (1) and (2) in the graph then the intersection point gives you the solution of the equation.

Equation (1) y=-x-3 is shown in blue line.

Equation (2) y=-x-3 is shown in red line.

The intersection points of both the equation are (-3,0) and (4,-7).

Therefore, The solution of the equation graphically are (-3,0) and (4,-7).

Refer the attached figure below.

Answer:

Step-by-step explanation:

  • A \cap C denotes the set of elements in both A and C, which is \{20, 24, 28\}.
  • B^{C} denotes the complement of set B, which is the set of all elements that are in the universal set that are not in set B. In this case, this set is \{3, 4, 5, 6, 8, 11, 13, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28\}
