Answer:
252, 253, 254
Step-by-step explanation:

253 is the median. so the multiples will be 252, 253, 254
First of all, you figure out that -4 < 3, so you use the first function definition. Then you put -4 wherever you see x.
.. f(-4) = (-4)^2 -5
.. = 16 -5
.. f(-4) = 11
The answer is 25 but i can't exactly show how
2(c+7)=2c+14
Use distributive property
2*c +2*7
2c+14=2c+14
Hope it helps!
The first option is the right one
