Answer:
- The function is injective but nor surjective
Step-by-step explanation:
<u>We see that:</u>
<u>For any x₁ and x₂ ∈ N, </u>
- f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers
It it confirmed one-to-one, hence it is injective
<u>Check the surjectivity:</u>
f(x) = y ∈ N
<u>Let y = 2, then:</u>
Since x is not natural, the function is not surjective
Answer:
They are on the same line
Step-by-step explanation:
<em>Hello there, and thank you for asking your question here on brainly.
<u>Answer: The three different types of angles are an acute angle, which is an angle that is an angle that measures from 1</u></em>° <em><u>to 89°. A right angle, that specifically measures to 90</u></em>°. <em><u>Finally, an obtuse angle that measures from 91° to 179°. An angle that also measures 180° is a straight line, and is called a straight angle.
</u>Hope this helped you! ♥<u>

Based on the information given, the equation to represent the situation will be x + 820.
Let last months car production be represented by x.
From the information given, we are told that a car corporation produced 820 more cars this month than it did last month.
Therefore, the equation to represent this month's car production will be:
= x + 820
