For the following piece wise functions, evaluate for the given value of x please help with this one

Question

f(x)={−2x+2,x≤3

−1,x>3

Evaluate the function when x=5

and Evaluate the function when x=3.

Answer 1

Answer 2

Formatting issues make some student questions difficult to read or interpret.  So at the risk of redundancy, I will rewrite what I think the student meant:

   f(x) = -2x + 2  when x <= 3

             -1          when x > 3

  

f(5) = -1  since any domain element > 3 has a range element = -1

f(3) = -4   since x = 3 is in the domain portion of the “first piece” of the function’s definition.

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