Question

PLEASE explain ..............

Answer 1

Explain what?

Answer 2

rewrite equation into vertex form
y=x^2 + 14x +50

Answer 3

@Aylin

Answer 4

@CalebBeavers can you help me with this ??

Answer 5

X^2+14x= y+50
X^2+14+49=y+50+49
is this right?

Answer 6

y = (x^2 + 14x) + 50 y = (x^2 + 14x + 49) + 50 - 49

y = (x + 7)^2 + 1

Answer 7

So, that gives a vertex of (-7, 1) which in this case is a low point on a parabola opening upwards.

Answer 8

soo y = (x + 7)^2 + 1 is the vertex right?

Answer 9

The general form for the vertex equation is:

y = a(x - h)^2 + k where (h, k) is the vertex.

Answer 10

That is the vertex form of the equation. The actual vertex is (-7, 1)
