(x) = |2 - x| + |4 - x|

f (-3) = 12 and f (-5) = 16

f(x) = |2 - x| + |4 - x|

To find f(-3) and f(-5), substitute the values in for "x" and simplify.

I'll do the first one, you can then do the other one:

f(-3) = |2 - (-3)| + |4 - (-3)|

f(-3) = |2 + 3| + |4 + 3|

f(-3) = |5| + |7|

f(-3) = 5 + 7

f(-3) = 12
