Answer:
xy
Step-by-step explanation:
x + y = xy because of the addition sign
A. Yes, the value of this function is 8 when x is 15.
B. False. I noted right away that the ordered pair (0,5) is not included, and some of the ordered pairs included do not represent the given function.
C. Yes, f(5) = 6. See (A) above.
D. False. The range of this function is the set of integers between 5 and 13 inclusive.
Enlargement: Anything higher than 2
Example: (2,2)
scale factor:4
Multiply coordinate by 4
New coordinate: (8,8)
Reduction: Anything less than 1
Example: (4,4)
Scale factor: 1/2
Divide coordinate by 1/2
New coordinate: (2,2)
HOPE THIS HELPS YOU! ^_^
You can split this shape into two shapes; a rectangle on top and a horizontal rectangle underneath. The top rectangle would be 4 x 2 = 8 square units, and the bottom rectangle would be 7 x 1 (3 - 2) = 7 square units. Now you just add these to get 15 square units. I hope this helps!
