Find the value of (3 + 4)2
elena55 [62]

Answer:

14

Step-by-step explanation:

We solve this by using 2 to open the bracket

(3+4)2 is the same as 2(3+4)

2(3)+2(4)

=6+8

=14

OR

(3+4)2 is the same as 2(3+4)

So we can solve the one inside the bracket first

=2(7)=14

What is the range of the function graphed below?
Dmitriy789 [7]

Answer:

Negative 3 less-than y less-than-or-equal-to 3

Step-by-step explanation:

remember, a closed dot means includes , and an open dot means does not include

[closed dot]

(open dot)

the range is all possible y-values. so, all y values shown are

3               which it includes

to -3            which it excludes  / does not include

so, all y values are greater than -3 and less than or equal to 3
