Question #1

HS.A-REI.11

let f(x) = |x + 5|

let g(
x) = |x|

let e(x) = |x - 5|

The three functions are graphed above on the same coordinate plane.

Is point A a solution for 
f(x) = g(x) ?  

Is point A a solution for g(x) = e(x) ?  

Is point C a solution for f(x) = g(x) ?  

Is point D a solution for f(x) = e(x) ?  

The solution set for all 3 functions is the values of where f(x) and g(x) and e(x) are  

therefore the solution set for all 3 functions from least to greatest is { , }
