Vertex form of an equation for a parabola looks like this:
f(x) = a(x-h)² + k
(h,k) is the vertex. Just plug in the values (3,-2)
f(x) = a(x-3)² - 2
Now use the point (5,-1) to find "a" so that the equation goes through that point.
-1 = a(5-3)² - 2
-1 = a(2)² - 2
-1 = 4a - 2
-1 + 2 = 4a
1 = 4a
1/4 = a
put that into the equation to get the answer
f(x) = (1/4)(x - 3)² - 2

Answer: -1/9
Step-by-step explanation: use the slope equation (y2 - y1) - (x2 - x1)
9 - 8 / -2 - 7
1/-9

Answer: Once
Step-by-step explanation: If you do 100 - 10 you get 90 as result, therefore you don't have 100 anymore making the only logical answer to this "ONCE".
