(x+4)(x-4)
Calculate the IQR (Interquartile Range) if Q1 = 25 and Q3 = 40.
what is 15
Find the x-coordinate of the vertex of f(x)=x2-6x+5
3
Distribute (x+3)(x+2)
x2+5x+6
Evaluate: f(3)=x2−4x+1
What is −2
factor 2x2+7x+3
(2x+1)(x+3)
The IQR represents this fraction of the data.
What is the middle 50%
The vertex of a parabola is (−3,5). If the parabola opens upward, is the vertex a maximum or minimum?
What is minimum?
subtract and simplify (3x2+5x-2)-(x2+2x+1)
2x2+3x-3

4x2-36
4(x+3)(x-3) or 2(x+3)*2(x-3)
If two box plots have the same median but different IQRs, what can you conclude about the data sets?
What is: They have the same typical value (center) but different spread/variability (or one dataset is more consistent than the other)?
