B. -2
C. 3
Answer:
Option A i.e. y = - 3 is not in range of the piece wise function graphed.
Step-by-step explanation:
The range of a function y = f(x) is given by the possible values of y for the possible domain (x-values) of the function.
Now, it is clear from the graph of the function that the value of y never goes below y = - 2.
The graph is drawn in such a way that any value of y less than - 2 and greater than - ∞ is not in the range of the function.
Therefore, option A i.e. y = - 3 is not in range of the piecewise function graphed. (Answer)
B) (-1,1),(-1,5),(-6,1)
C) (-1,1),(-1,4),(-7,1)
D) (-1,1),(-1,5),(-7,1)
Answer:
D) (-1,1),(-1,5),(-7,1)
Step-by-step explanation:
The vertices of the triangle shown in the coordinate plane are: (-1,1), (-1,3), (-4,1)
The legs are in the ratio:2 : 3
For triangle with vertices A) (-1,1),(-1,4),(-6,1) ,
The legs are in the ratio: 3:5
For triangle with vertices:
B) (-1,1),(-1,5),(-6,1)
The legs are in the ratio:
4:5
For the triangle with vertices:
C) (-1,1),(-1,4),(-7,1)
The legs are in the ratio:
3:6=1:2
For triangle with vertices:
D) (-1,1),(-1,5),(-7,1)
The legs are in the ratio:
4:6=2:3
Therefore the correct answer is D.
Because similar triangles have their corresponding sides in the same proportion.
