To find the reciprocal of a number or fraction, just flip the numerator and denominator. Whole numbers are always over 1.
2 =
The reciprocal of
or .5 (one-half)
The reciprocal of
Answer:
Plug g(x) into all the x values in your f(x) and the answer is 3 because it makes the denominator 1-1 which makes it 0 and is thus discontinuous
Step-by-step explanation:
The polynomial that represents the length is:
h(x) = 11x + 1.
<h3>
How to find the length?</h3>
We know that the area of the top surface is given by:
f(x) = 66x^2 + 17x + 1
And the width of the top surface is:
g(x) = 6x + 1.
We can assume that the length, h(x), is another polynomial of degree 1, so we can write:
h(x) = a*x + b
Now, the area is the product of the width and the length, so we have:
f(x) = g(x)*h(x)
f(x) = (6x + 1)*(ax + b)
= 6ax^2 + (6b)x + (a)x + b
= (6a)x^2 + (6b + a)x + b
Now let's compare this with f(x), correspondent coefficients must have the same value.
66x^2 + 17x + 1 = (6a)x^2 + (6b + a)x + b
Then we have:
66 = 6a
17 = 6b + a
1 = b
From the first equation we have:
66/6 = a = 11
And from the third:
b = 1
Then the length is:
h(x) = 11x + 1.

Answer:
the second option [2, +infinity)
Step-by-step explanation:
the range is the interval or set of valid y (functional result) values of the function.
so, for x<0 the result is always 3.
for 0<=x<2 do we get results between 2 and 6.
for x>=2 we get results between 6 and infinity.
so, the combining interval of all possible y values is
[2, +infinity)
2 is included, infinity as usual not (as this is not a value).
