Answer:
22.5
Step-by-step explanation:
10 x 4.5 = 45 divided by 2 is 22.5
The answer to the problem is -5
Answer:
The vertex is (3,4)
Step-by-step explanation:
f (x) = x^2 - 6 x + 13
Completing the square
-6/2 = -3 and squaring it = 9
= x^2 -6x +9 +4
= ( x-3) ^2 +4
The equation is now in vertex form
a( x-h) ^2 +k
where the vertex is ( h,k)
The vertex is (3,4)

We need to find thr rate of change (slope) of the line joining these two points ~





Slope of the line (m) joining the two points is 2 ~
