We have 3 9/16 = 57 / 16 = 3.56;
4 3 / 5 = 23/5 = 4. 60;
4 7/8 = 39 / 8 = 4.87;
4 1 / 2 = 9 / 2 = 4.50;
3 1 / 2 = 7 / 2 = 3.50;
3 3 / 8 = 24 / 8 = 3;
Only, 4.50 > 3.56 and 4.50 < 4.60;
Our number is 4 1 / 2.
Answer:
4) is the opposite function of 3), and vice versa. Because f(x) =2x-1 and its opposite f(x)=-2x+1. And we can see them both in pictures 3 and 4.
Step-by-step explanation:
A piecewise function is a function defined in a sequence of intervals. The most known piecewise function is the modular function. (1st picture)
An opposite function is given by f(x)=-x of f(x)=x
The following pictures describe the following functions:
1) f(x)=-|2x|+2
2) f(x)= 2.34x-2.34 and f(x)= -2.34x-2.34
Notice how the second function express the opposite line, by the opposite angular coefficient.
3) f(x) =2x-1 and f(x)=-2x+1
4) f(x) = -2x+1 and f(x)=2x-1
Different intervals but the same functions are graphed in 3 and 4. So the graph of f(x)=2x-1 and its opposite f(x)=-2x-1

Answer:
Step-by-step explanation:
|x+3|+7>8
|x+3|>8-7
|x+3|>1
either x+3>1
x>2
or x+3<-1
x<-4
