Question

Which function is graphed? A f(x)=x−1 B f(x)=−1 C f(x)=1 D f(x)=x+1

Answer 1

The answer is B.

f(x) = x-1 will give you a graph of linear function also known as "line"

f(x) = -1 will give you the exact graph like the picture. It's the graph of constant function.

f(x) = 1 will give you a graph of constant function like f(x) = -1. However the graph passes (0,-1) , not (0,1)

f(x) = x+1 will give you a graph of linear function.

Linear Function doesn't give you either vertical or horizontal line except for constant one.
