Answer:
Step-by-step explanation:
Let's solve this using our formula for exponential functions:
where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):
. Anything raised to the power of 0 is 1, so that means that
a = 3. We will use that value along with the x and y from the second coordinate to solve for b:
. b to the first is just b, so our equation is
6 = 3b and
b = 2.
Our equation then is
, the third choice down.
Answer:
Last Option moved units right
Step-by-step explanation:
If we have a function f(x) and we want to move it horizontally then we make the transformation:
If then the graph of f(x) moves horizontally h units to the right
If then the graph of f(x) moves horizontally h units to the left.
In this case we have the function and the transformation is performed to obtain
Notice that in this transformation
<u><em>Then the graph of moves horizontally
to the right</em></u>
