Question

Which function is a linear function?
A. f(x)=x^3+x
B. g(s) = 1 − 4s
C. h(t)=2t+1/t
D. f(r)=√r

Answer 1

Well what do you think?

Answer 2

Linear function is a kind of function where you will see line if graphed.

Answer 3

Well, at first glance, we can mark out options A. and D. because they are the cubing and square root functions. Both of which are not linear.

Answer 4

Option C. is not a linear function either. It's the reciprocal function stretched vertically and shifted over one unit...it has to be option B.
