Question

What affect does the "k" value have on the function f(x) = log(x)?
A. The "k" value reflects the function across the x-axis.
B. The "k" value moves the graph up or down.
C. The "k" value moves the graph left or right.
D. The "k" value stretches the graph vertically by a factor of absolute value of k.

Answer 1

I'm assuming The "k" value moves the graph up or down., but tbh I have very little idea

Answer 2

Set it up as you would a quadratic equation, and compare it, that is a pretty good way I'd think :)

Answer 3

Yes, that's right!

Answer 4

Is that correct? @ganeshie8 :)

Answer 5

if batman says so, it has to be right :)

Answer 6

Why is it correct @Astrophysics

Answer 7

Do you remember the quadratic form f(x) == a(x-h)+k?

Answer 8

wheres batman?

Answer 9

general form for log
\[y = a \log(x-h) +k\]
the "k" does indeed move graph up/down because it is adding/subtracting to the y-value

Answer 10

Yup!
