Answer:
f(-10) = -19
f(2) = 4
f(-5) = -9
f(-1) = 1
f(8) = -5
Step-by-step explanation:
This is relatively simple if you understand the concept. All you have to do is take each number and then look at each inequality to see where it fits.
For example, if you take 2 and look at the first inequality, you see that 2 is not less than or equal to 5. Now if you look at the second inequality, you see that 2 is both greater than -5 and less than 5. Since 2 fits in the second inequality, you plug it into the second equation.
These functions where you have to see where the x-value fits are called piecewise functions and you will see them a lot in higher level math.
(disclaimer: I evaluated the numbers quickly, so I would doublecheck it, but I am pretty sure I didn't mess up)
4375 is 4000 rounded, to round to the nearest thousand you look at the hundreds place which is 3 and since it is less than 5, you round down
The answer is 1 because when you subtract 972 from 932 you get 40. Then u add 812 and 40 to see if u get 852 and u do, so add 40 to 852 and you get 892.
The answer is C, because to find IQR you have to find the difference (subtract) of the first and third quartile
