If the width of a rectangular piece of wood is x + 2 inches long and the length is three times as long with an additional inch added, what is the area of the wood?
a. 3x² + 12x + 12
b. 3x² + 12x + 14
c. 3x² – 13x + 14
d. 3x² + 13x + 14

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

)

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
