Answer:

A

Step-by-step explanation:

To figure out whether a graph is a function, you need to use the line test.  The line test is where you pass a vertical line over the graph.  If the vertical line crosses the graph more than once, the graph is not a function.  You can use your pencil as a vertical line.

Graph 1 is not a function because the vertical line will cross the graph twice.

Graph 2 is a function because the vertical does not cross the graph twice.

Graph 3 is not a function because the vertical line will cross the graph twice.

A small business assumes that the demand function for one of its new products can be modeled by p = Cekx. When p = $40, x = 1000
Maru [420]

Answer:

C= 82.1116

k=-0.0007192

Step-by-step explanation:

p=Ce^{kx}\\40=Ce^{k1000}\\30=Ce^{k1400}\\

Applying logarithmic properties yields in the following linear system:

ln(40) = ln(C) + 1000k\\ln(30) = ln(C) + 1400k

Solving for k:

ln(40) = ln(C) + 1000k\\ln(30) = ln(C) + 1400k\\400 k = ln(30)-ln(40)\\k=-0.0007192

Solving for C:

40=Ce^{-0.0007192*1000}\\C= \frac{40}{e^{-0.0007192*1000}}\\C=82.1116

C= 82.1116

k=-0.0007192
