Answer:
The vertex is (4,-17)
Step-by-step explanation:
To find the area of this entire shape, we must divide it into two rectangles.
The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.
The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.
To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.
8 * 3 = 24 cm^2
3 * 4 = 12 cm^2
24 sq cm + 12 sq cm = 36 square centimeters.
Therefore, the area is 36 square centimeters. Hope this helps! :)
Answer:
Step-by-step explanation:
The graph certainly is, if you ignore the fact that you don't know what the equation for the graph is.
Each x has only 1 y associated with it. That's the definition of a function. This one presumably follows that definition, but I caughten you, without the equation, you can't be sure.
