Answer 1

Hello! Welcome to QuestionCove.
Where are the choices that your question ("Which of the following") refers to?

Answer 2

Which of the following is a linear function?

y = x3 + 1
five over sixx = y − 4
y = 8x2
y = one over five x

that is the actual question

Answer 3

Ah, sorry to say I am not very good at this kind of math. Kind of rusty here.
I'll tag some people who are better suited to answering your question with more accuracy.

Answer 4

to be a linear function:
- x cannot be raised to a power greater than 1 (no x^2, x^5, etc)
- x cannot appear in the denominator of an expression (this implies x has a negative exponent)

with these facts in mind, which of the 4 functions fits this criteria?
