Answer:
vertex: (2, 5)
Step-by-step explanation:
y=3(x−2)2+5
this is a parabola because of one variable squared and the other one is not so now write it in the standard form of parabolas which it is = to
______
Vertical :
(x−h)2=4p(y−k)
Horizontal:
(y−k)2=4p(x−h)2
vertex = (h, k)
this y=3(x−2)2+5 equation is vertical since x is squared
subtract 5 from both sides:
y−5=3(x−2)2
divide both sides by 3:
(y−5)13=(x−2)2
vertex:
(2,5)
(2, 5)
The x coordinate is the number inside the parentheses, but with the opposite sign, 2
The y coordinate is the number at the end
