Question

evaluate f(3) for f(x)=-x^2+2x, x<1
-2x+3, x>1

Answer 1

(3)=-x^2+2x, x<1
f(3)=−(3)^2+2(3)
f(3)=-9+6= -3

-3<1

The other one is false because -3 is not greater than 1. Here is why:

f(3)= -2x+3, x>1
-2(3)+3= -3

-3>1 is not true.

Answer 2

OK. That's what I sort of thought but wasn't sure.
