(03.04) What is the vertex of the graph of y = −4(x + 2)2 + 5? (1 point) (2, 5) (−2, 5) (5, −2) (5, 2)

Gnoma [55]

Answer:

(-2, 5)

Step-by-step explanation:

The form you're trying to match is the vertex form of the equation of a parabola:

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

You have ...

y = -4(x +2)^2 +5

Comparing forms, you see that a=-4, h=-2, k=5.

Then the vertex (h, k) is (-2, 5).

How is the graph of y= square root x+3 translated from the graph of y = √x

Law Incorporation [45]

9514 1404 393

Answer:

3 units left

Step-by-step explanation:

Replacing x in a function with (x-h) translates the graph to the right by h units. Here, you have h = -3, so the graph is translated left 3 units.
