Can someone please answer this? I'm completely confused

The IQR is the best measurement of spread for movies than it is for basketball games.

Step-by-step explanation:

Interquartile range or IQR will be a better measurement than standard deviation when the data skewed. To determine if the data skewed, you can take the middle lines of the box and compare the left/right box size.  

The data for movies is skewed to the left side since left box larger than right. The data for games is not skewed since the box is relatively have similar size.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
