Find the difference quotient for f(x) = 3x2 – 12.
_x+_h
The difference quotient for f(x) = 3x2 – 12 is 6x + 3h
How to determine the difference quotient?The function is given as:
f(x) = 3x^2 – 12.
Calculate f(x + h)
f(x + h) = 3(x + h)^2 – 12
The difference quotient is then calculated using:
[tex]f'(x) = \frac{f(x + h) - f(x)}{h}[/tex]
This gives
[tex]f'(x) = \frac{3(x + h)^2 - 12 - 3x^2 + 12}{h}[/tex]
Evaluate the difference
[tex]f'(x) = \frac{3(x + h)^2- 3x^2}{h}[/tex]
Expand
[tex]f'(x) = \frac{3x^2 + 6xh + 3h^2- 3x^2}{h}[/tex]
Evaluate the difference
[tex]f'(x) = \frac{6xh + 3h^2}{h}[/tex]
Evaluate the quotient
f'(x) = 6x + 3h
Hence, the difference quotient for f(x) = 3x2 – 12 is 6x + 3h

A square board was attached to a wall. The board was divided by four squares and each square was colored either black or white. How many possible combinations of such coloring are there, if we cannot rotate the given board? PLEASE HELP QUICK! IM NEW AND I NEED ANSWERES! I HOPE BRAINLY DEOS NOT FAIL ME!
Answer:
24 combinations
Step-by-step explanation:
For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.
Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)
By the way, welcome to brainly.

Answer:
x^2 -5x +6 = 0
Step-by-step explanation:
Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...
(2x -1)(3x -1) = 0 ⇒ roots 1/2, 1/3
Then the factoring of the equation with reciprocal roots is ...
(x -2)(x -3) = 0
x^2 -5x +6 = 0

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?
Answer:
hotdogs 3.45
rolls 2.60
Step-by-step explanation:
6h + 8r = 41.5
r=h-.85
6h + 8(h-.85)=41.5
6h + 8h - 6.8 = 41.5
14h = 41.5 + 6.8
14h = 48.3
h=48.3/14
h=3.45
r=3.45-.85=2.6

The measure of an angle is 66° . What is the measure of its complementary angle ?
Answer:
24º
Step-by-step explanation:
90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.
Answer:
The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).
Step-by-step explanation:
A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.
Let's call the smaller angle x
We also know that the larger number is 66° more than the smaller. This gives us:
x+x+66°=180°.
x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.
Now we can simplify this by subtracting 66° from both sides.

Plz help with graph polynomial
Answer:
(x + 1 ) is a factor
Step-by-step explanation:
Given a polynomial with roots x = a, x = b , then the corresponding factors are
(x - a) and (x - b)
From the graph
The roots are x = - 1 and x = 4 , thus factors are
(x - (- 1)) and (x - 4) , that is
(x + 1) and (x - 4)
(x + 1) is the required factor
