Paul tosses a quarter off the Main Street bridge into the St. John’s River. The distance, in feet, the quarter is above the water is modeled by the equation
d( t ) = -12t^2 + 48t + 100, where t represents time in seconds.

Part A: From what height was the quarter tossed?

Part B: How long does it take the quarter to reach its maximum height?

Part C: What is the maximum height of the quarter?

Part D: How much time does it take for the quarter to hit the water?

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

)
