Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7
union of the two parts of y: 1≤y<7
[1,7) is the answer.
Answer:
Except table 2, all tables have greater unit rate than the graph.
The required arrangements of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6
Step-by-step explanation:
Formula for unit rate :
From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is
Similarly, we need to calculate the unit rate for each table.
Except table 2, all tables have greater unit rate than the graph.
The required arrangement of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6

Answer:
4.5>2.89
Step-by-step explanation:
This question is asking for the comparison between the values of both numbers. 4.5 is greater than 2.89, and this can be written as 4.5>2.89
