Which of the quadratic functions is written in vertex form?
y=(x+1)(x-5)
y=2x^2+3x-5
y-4=3(x-5)
y-7=-2(x+3)^2

y-7=-2(x+3)^2

Step-by-step explanation:

Vertex Form

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

move the 7 by adding it to both sides in order to get it into vertex form.

c. side angle side. u shares the same sides

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
