f(x)= 5x+1if x<1

        2x if 2 </= x</=6

        2-2x if x>6

find following if possible f(2) f(1.5) f(7) 

Do I just plug these in for x and solve? for example f(2)    5(2)+1 if (2) < 1     10+1 if 2<1       11 if 2<1

am i doing this right or no

the question doesnt look right...

f(x)= 5x+1if x<1

        2x if 2 </= x</=6

        2-2x if x>6

the value of x between 1 and 2 is missing...

like if x =2 you should be using that corresponding equation...here the value for x=2 and x= 1.5 is missing

for x=7, you should be using 2-2x

do you understand?
inbox me if you done.
