Question

Which graph represents the function of f(x) = 4x^-16/2x-4 ?

Answer 1

a.

Answer 2

b.

Answer 3

c.

Answer 4

or d.

Answer 5

just factor the numerator and denominator... remove common factors and you get a straight line.

find the intercepts and you'll have your line.

Answer 6

4x^ ?????

Answer 7

also. before you factor you have to find the restriction on x. so you know where the graph is discontinuous

Answer 8

which one is it?

Answer 9

\[\frac{4x^2-16}{2x-4}=\frac{4(x^2-4)}{2(x-2)}=\frac{2(x+2)(x-2)}{x-2}=2(x+2)=2x+4\] is a start

Answer 10

your answer is whatever line has slope \(2\) and \(y\)-intercept \(4\)

Answer 11

oh i see, you have to such lines, pick the one with the hole in it at \((2,8)\) because \(x\) cannot be \(2\)

Answer 12

is it c then?
