Answer:

The last one, D it is not a function because the domain (x) does not repeat.

Step-by-step explanation:

To find whether it is a function or not ALL YOU NEED TO DO is check if the domain (x) repeats, it also includes negative numbers like if the domain is

-2, 3, 5, 2  it will be a function because none of these numbers repeat. Yes the number "-2, and 2" repeat BUT one is negative and one is positive, therefore it is a function because they are different numbers when they are negative and positives.

Also just wanted to mention if the (y) repeats it does not matter. It can repeat even a million times, but if the domain numbers (x) do not repeat, therefore it is a function.

What is the area of a triangle with vertices (3,0) (9,0) (7,6)
Nezavi [6.7K]

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices (x_1,y_1),(x_2,y_2),(x_3,y_3) is given by the determinant of the following matrix:

A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|

In this question:

Vertices (3,0) (9,0) (7,6). So

A = \pm 0.5 \left|\begin{array}{ccc}3&0&1\\9&0&1\\7&7&1\end{array}\right|

A = \pm 0.5(3*0*1+0*1*7+1*9*7-0*7*1-0*9*1-3*1*7)

A = \pm 0.5*(63-21)

A = \pm 0.5*42 = 21

The area of the triangle is of 21 units of area.
