Question

How to evaluate this f (x) = -x^+1 for x =-3

Answer 1

Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!

Answer 2

Substitute x with -3

so f(3)=-(3) +1
=-2
