The value of your father's car when bought was $30,000. If it loses 10% of its value every year, how long until the vehicle is only worth $20,000?

10 years

Step-by-step explanation: 10x10=100, 10 years and 10%.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

1/5^2 = 7.56/45
