Question

Please help me!! This are piecewise functions.
Evaluate the following for the given function.
f(x)={ 3x-7, if x is less than or equal to 2
{6-2x, if x>2
1. f(2) 2. f(-3) 3. f(5)

Answer 1

f(x)= [3x-7, x \le2\]
\[6-2x, x >2\]
You would have to plug in the f(#) into the equation that it falls into.
So for f(2), you would use the first equation since x is less than or equal to 2.
3(2)-7
=6-7
=-1

Answer 2

Ok, I get it now. Thank you!
