1 answer:
Citrus2011 [14]2 years ago
6 0

Answer:

Only C) The function is increasing on the interval (-2,∞)

Step-by-step explanation:

As we know square root function is only defined for all the value of x greater than or equal to 0 . That being said, the function 2\sqrt{x+3}-3 is undefined on the interval <em>(</em><em>-</em><em>∞</em><em>,</em><em>-</em><em>2</em><em>)</em><em>,</em><em>(</em><em>-</em><em>∞</em><em>,</em><em>0</em><em>)</em><em> </em>.So we can eliminate a) and b).As for the second option, Although interesting, It's incorrect. On the interval (-2,∞) , it's increasing not decreasing. Hence, Option C is correct!

What is the vertex for the function f(x) = 3(x – 2)2 + 4?
Gala2k [10]

Answer:

The vertex for the function f(x) = 3(x – 2)2 + 4 is at (2, 4).

Step-by-step explanation:

Find the vertex for f(x) = 3 (x - 2)^2 + 4

f(x) = 3 (x - 2)^2 + 4 can also be written as:

y = 3 (x - 2)^2 + 4

To find critical points, first compute f'(x):

d/(dx)(3 (x - 2)^2 + 4) = 6 (x - 2):

f'(x) = 6 (x - 2)

Solve 6 (x - 2) = 0

6x - 12 = 0

6x = 12

x = 2

iI you substitute x = 2 in 3 (x - 2)^2 + 4 then you get:

y = 3 (x - 2)^2 + 4

x = 2

y = 3 (2 - 2)^2 + 4

y = 3 (0)^2 + 4

y = 3 (0) + 4

y = 4

Answer: The vertex for the function f(x) = 3(x – 2)2 + 4 is at ( 2, 4 ).
