SOLUTION: Find f(3) if f(x)= { 2-x, if x>3 and x+2, if x≤3}

Question 634664: Find f(3) if f(x)= { 2-x, if x>3 and x+2, if x≤3}

This is a piece wise-defined function.
We cannot use 2 - x because the value of x
must be less than 3 or = 3.
So, we replace x with 3 in the expression
x + 2.
f(3) = x + 2 if x is less than 3 or equal to 3.
f(3) = 3 + 2
f(3) = 5
Done!
