Answer:
Nice to hear that, congrats with practice 7.3
200 / 8 = 25
scale factor is 1:25 or 0.04
Answer:
f(x)= (x+8)^2 + 200
Step-by-step explanation:
-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).
H is the x coordinate and K is the y coordinate
