Answer:
Step-by-step explanation:
we know that
A quadratic function in factored form is equal to
where
a is the leading coefficient
x_1 and x_2 are the zeroes of the function
substitute the given values
Find the value of a
Remember that
For x=0 ----> f(0)=4
substitute
so
Answer:
Option D.The decrease in the value of the car, which is 8%
Step-by-step explanation:
we have a exponential function of the form
where
y is the value of the car
x is the time in years
a is the initial value
b is the base
r is the rate of decrease
b=1+r
In this problem we have
a=$24,000 initial value of the car
b=0.92
so
0.92=1+r
r=0.92-1=-0.08=-8%-----> is negative because is a rate of decrease
