We may determine the degree of a polynomial by observing the number of times it has intersected the x-axis
Above in the picture we can tell that it has intersection coordinates of
((-2,0) (-1,0) (1,0)(2,0)
Therefore we have a 4th-degree polynomial (which makes it even degree)
And since both of his sides are going infinitely upwards then the leading coefficient is positive.
Hope i helped.
Answer:
Option B and C are correct.
Step-by-step explanation:
Inverse function: If both the domain and the range are R for a function f(x), and if f(x) has an inverse g(x) then:
for every x∈R.
Let and
Use logarithmic rules:
then, by definition;
=
Similarly;
for and
then, by definition;
=
Similarly,
g(f(x)) = x
Therefore, the only option B and C are correct. As the pairs of functions are inverse function.
The correct option regarding whether the sum of a rational number and an irrational number is always irrational is given by:
Yes. The claim is correct because √ 16 + π = 4 + π , and 4 + π is an irrational number.
<h3>What are rational and irrational numbers?</h3>
- Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
- Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.
The sum of a terminating decimal with a non-terminating decimal always results in a non terminating decimal, that is, the sum of a rational number with an irrational number is always irrational, and the correct option is given by:
Yes. The claim is correct because √ 16 + π = 4 + π , and 4 + π is an irrational number.
