Answer:
Options (2), (3) and (4) are correct.
Step-by-step explanation:
The given function is f(x) =
1). First derivative of the function = f'(x) =
f'(x) =
Since derivative is negative, function will be decreasing everywhere.
Therefore, Option (1) is incorrect.
2). Since value of the function is true for every value of all real values of x.
Domain of the function is (-∞, ∞).
Therefore, Option (2) is correct.
3). For the given domain, range of the function will be all real values of y Or (-∞, ∞)
Therefore, Option (3) is correct.
4). Function 'f' when reflected across x axis, equation of the reflected function will be g(x) = .
Therefore, Option (4) is correct.
5). For a point (3, -27),
-27 =
Therefore, Option (5) is incorrect.
Answer:
a) 2x^4 + 8x^3 + x^2 + 3x
b) evaluate this polynomial at x = 10
Step-by-step explanation:
Hi!
a)
The product of a sum is the sum of the products, having said this:
b)
We can use the result from part a and consider x = 10.
First lets take the first polynomial
Knowing that every number (excepting probably 0, which could be undefined for some or 1 for others) to the power of 0 is one:
Which is the initial number
Now lets conisder the product of the polynomial times x and evaluate it at x=10:
We can now see that teh rule is treu because we can see the whole number as a sum of numbers from 0 to 9 multiplied by a power of 10, and when it is multiplied by 10, each power increases by one, and at the end, the final result is adding a zero at the end
