Which graph shows g(x) = (1/3)^x-2 +6?


Answer:
Top right
Step-by-step explanation:
One of the main aspects that can be used in this type of exercises is the value on the ordinates axis (another could be the 0 roots).
Let's look at the ordinates term of the function g(x) = (1/3)^x-2 +6.
We get the independent term replacing the x with 0. If we do so we have:
g(0)= 1/3^(-2)+6= 1/(3^(-2)) = 3^2 + 6 = 9+6=15
So our function must cut the ordinates axis in 15. The only one that fits this requirement is the second on the image with 4 functions (the top right).
This is the right one.
Answer:
Step-by-step explanation:
The question is asking for a translated function, where the original is:
[tex]f(x)=(\frac{1}{3})^{x}[/tex]
So, we need to find the graph of:
[tex]g(x)=(\frac{1}{3})^{x-2}+6[/tex]
We observe that the expression is subtracting two units from the x, and adding 6 units to the y.
Subtracting units to x, we will translate the function to the right, in this case, 2 units.
By adding 6 units to y, we are translating the function upwards 6 units.
So, the right graph should be a similar function, translated 2 units to the right and 6 units upwards.
Therefore, the right graph is the second one, which is upper right corner.
