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 ).
The answer is 4x-1 hope it helps. :D
Answer:
The number of shirts to be purchased for price to be same is 6 .
Step-by-step explanation:
Given as :
The price for cool shirt = $ 8
The shipping charge for cool shirt = $ 13
The price for Tees = $ 7.50
The shipping charge for Tees = $ 16
Now, Let The number of shirts = S
So , According to question
∵ price to be same for both companies
∴ $ 8 × S + $ 13 = $ 7.50 × S + $ 16
Or, $ 8 × S - $ 7.50 × S = $ 16 - $ 13
Or, 0.5 S = 3
∴ S =
I.e S = 6
Hence The number of shirts to be purchased for price to be same is 6 . Answer

Step-by-step explanation:
Standard deviation is a statistic that measures the dispersion of a sample. The sample standard deviation measures the spread of data distribution of the sample. It is usually used to estimate the population standard deviation.
