Question

Use function notation to write the equation of the line.

A. f (x) = 3x

B. f (x) = 3

C. f (x) = –3

D. f (x) =0.3x

Answer 1

this is a constant function graph since its perpendicular to the y axis and parellel to x-axis...and also at x=0,y=3&x=1,y=3&x=2,y=3 so answer is y=3 which is f(x)=3

Answer 2

B there is no slope
