The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so

y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is  (2,3)

Answer:

(2,3)

Step-by-step explanation:

An equation of the form

a^{2}  + bx + c = 0

can be expressed in the Vertex Form:

y = a (x - h)^{2}  + k

where the vertex is always:

(h, k)

The vertex is the lowest or highest point of the parabola.

When we compare the two functions:

y = a (x - h)^{2}  + k

y = -1 (x - 2)^{2}  + 3

We can see that

a = -1

h = 2

k = 3

So the vertex is:

(h, k) = (2, 3)

I hope this helps!

Given AQRS-AXYZ, what is the value of tan(Q)?<br><br> A) 3/5<br> B) 3/4<br> C) 4/5<br> D) 4/3
iren [92.7K]

The answer is B.

Since ΔQRS ~ ΔXYZ, the value of tan(Q) is :

  • ∠Q = ∠X
  • tan(Q) = tan(X)
  • tan(X) = 3/4
  • tan(Q) = 3/4

Yes
if you had less than 2, the lines wouldn't cross each other and wouldn't form a triangle
