Answer:
the vertex is ( 3 , 3)
Symetric axis‘s equation: x = 3
Step-by-step explanation:
Let‘s name the function ” f ”
f(x) = y = 2x² - 12x + 21
the vertex has coordinates of ( -b/2a , f(-b/2a) )
-b/2a = 12/2(2) = 12/4 = 3
f(-b/2a) = f(3) = 2(3)² - 12(3) + 21 = 3
then the vertex is ( 3 , 3)
the symetric axis has the equation :
x = -b/2a
then
<em>Answer,</em>
<em>21 * 50 = </em><em>1,050</em>

(13•4) + (3•8) +3 = 79
The total cost is $79
Answer:
C
Step-by-step explanation:
Only the x values are affected.
So you add 5 to each of the x values.
0+5 = 5
-3+5 = 2
The points then become (5, - 5) and (2,-7)
The answer is C
