Answer:
D.
Step-by-step explanation:
0.72 = 72%
So that being the case, his car's value decreased by 72%
Answer:

Step-by-step explanation:
Use coordinates (2,1) and 3,10
The exponential equation is

Plug in the x and y values.xfor both functions of coordinates.


Divide the equation with the larger exponet by the other equation.

Substitute that in for one of the equations.

Solve for a.


So our exponetial equation is

from,
y = f(x)
then,
f(0)
this means that x = 0
from the graph x = 0 is found at C
y = -2.
All the best!
