Answer:
(2,-17) should be the minimum.
Step-by-step explanation:
The minimum of a quadratic function occurs at  . If a is positive, the minimum value of the function is
 . If a is positive, the minimum value of the function is 
 occurs at
 occurs at 
Find the value of 
x = 2
evaluate f(2).
replace the variable x with 2 in the expression.

simplify the result.



The final answer is -17
Use the x and y values to find where the minimum occurs.

Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =  , then
 , then
sin45° =  =
 =  =
 =  ( cross- multiply )
 ( cross- multiply )
x ×  = 9
 = 9 ( divide both sides by
 ( divide both sides by  )
 )
x = 9
