Answer:

f(x) = (8/3)^x

Step-by-step explanation:

Since f increasing, the base value must be greater than 1.

8/3 is the only base value greater than 1.

The base (3/8) would be a decreasing graph because it is less than 1.

The base (-3/8) would result in a wavering graphing passing the x-axis many times. (Because whether the result is negative depends on if x is odd or even.)

in (8/3)^(-x), it is the same as (3/8)^x by applying the negative exponent rule a^(-x) = 1/(a^x).

Answer:

The function in quadrant I, where y is increasing upward.

Step-by-step explanation:

The smaller x becomes, the larger f(x) becomes. The answer is that f(x) or y approaches infinity as x becomes smaller and smaller. This helps to understand why division by zero is undefined.

Here you go! Hope this helps!! :-)
