The product of two numbers refers to multiplication. Multiply 8.2 and 1.9.
8.2 • 1.9 = 15.58
There are two digits to the right of the decimal point. Your answer is: A.
The answer would be a negative number.
Say we have -3³.
That would be -3 x -3 x -3, which you would end up with -27.
On even exponents with a negative number, You would end up with a positive.
It most likely will be the initial value when dealing with a cost/value problem. By convention the initial value is set at 0 time.
For example, an exponential function of interest on a savings account or depreciation of a car. (0 years, initial value) As time progresses the value changes.
If the graph is not of a cost/value problem then it could be something else entirely or if for example you were trying to back calculate the inital value of something and chose the present year as 0 time. Initial value being the y-intercept is more or less determined by how the problem is set up and bit is simplest to set it as so.
