Determine the domain and range of the function f(x) = –|x| + 2.

Hello from MrBillDoesMath!

Domain: all x

Range:     f(x) <=2

Discussion:

The domain of abs(x) is all real x, and this is the domain of f.

As abs(x) >=0,    ( or   -abs(x) <= 0)

f(x) = -abs(x) + 2 <=  0 + 2 = 2

Thank you,

MrB

All real numbers

less or equal to 2

Step-by-step explanation:

oof

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
