Question

Which of the following functions would not graph as a straight line?
A) f(x)=-x^2-3
B) f(x)=2x^2/x+1/2
C) f(x)=3x-1/4
D) f(x) = –4x

Answer 1

Do you remember the equation for a linear line or slope?

Answer 2

Nope :/
i left my notes at school

Answer 3

You could graph each equation as well to determine if it's linear or not. Do you remember what your basic functions look like, for example x, x^2, abs x, etc?

Answer 4

I found the answer....A :)

Answer 5

and...

Answer 6

I presume there can be more than two answers?

Answer 7

There is more than one function I can see that will not graph a linear line.

Answer 8

A and B would both graph as parabolic, B having a vertical asymptote at x = -0.5
