<h3>Answer:</h3>
graph of a parabola symmetric about the x axis with x intercept at negative 5
<h3>Explanation:</h3>
A parabola that opens horizontally does not pass the vertical line test. You can draw a verticla line that intersects the curve in 2 places. A function must be single-valued, so can only have one y-value for any x-value.
It should be 15 because 48/3.2 is 15 and that means he swam 48 kilometers in 15 days
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
N = (8800)xln(7(2) + 9)
N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.
