In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) is called polynomial
i think by this definition you can find your answer by your self
Answer:
A. Yes, the point is defined, limit f(x) exists, and limit f(x) 0.
Step-by-step explanation:
Let be , a rational function is continuous at a value of if and only if denominator is different from zero. In particullar, .
Then, we find that function is continuous for every value of except . Thus, the function is continuous at , which is evaluated below:
Thus, correct answer is A.
Answer:
k = 5
Step-by-step explanation:
The given line is y = 4x - 14.
The given point is (k, k + 1).
For this point, x = k and y = k + 1.
You substitute these equations into the line's equation to find the value of k.
(x = k)
(y = k + 1)
y = 4x - 14
(k + 1) = 4(k) - 14
Solve for k.
k + 1 = 4k - 14
Subtract k from both sides.
1 = 3k - 14
Add 14 to both sides.
15 = 3k
Divide both sides by 3.
15/3 = k
Simplify.
5 = k
And that's the answer!
