Write a possible exponential function in y=ab^x form for the graph described below.
-> has a y-intercept of (0,3) and passes through the point (2,48)

Step-by-step explanation:

Any raised to the 0-th power will give 1. So

Once you know that, from the passing through (2,48) you get:

Notice that,even if -4 satisfies the condition, exponential functions are defined only and only if the base is positive and not equal to 1. (if the base was 1, you'd get an horizontal line, and with a negative base the function starts losing meaning in the real plane in a series of points.

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
