Find the range of the function f(x)=4x-1 for the domain {-1,0,1,2,3}

Question

A){-5,-30,7,11}
B){-5,-4,-3,-2,-1}
C){-11,-7,-3,1,5}
D){-5,-1,3,7,11}
Can someone help, am i right is the answer B????

Answer 1

f(-1) = -5, so C is out
f(0) = -1, so only D is left

you should check the other points, but they look good. Note that y increases by 4 at each step, since the slope is 4.
