Question

What affect does h = 2 have on the function f(x) = log(x)?
A. The graph moves 2 units to the right.
B. The graph moves 2 units to up.
C. The graph moves 2 units to the left.
D. The graph is stretched by a factor of |2|.

Answer 1

B. The graph moves 2 units to up.

Answer 2

this works just like the quadratic form:
y = a(x - h)² + k
i.e.
f(x) = alog(x - h) + k
so
h moves the curve left and right
k moves the curve up and down
