Answer:
y- intercept = - 6
Step-by-step explanation:
The y- intercept is where the graph crosses the y- axis.
Let x = 0 and substitute in to the equation, that is
y = 0² - 3(0) - 6 = 0 - 0 - 6 = - 6 ← y- intercept
What?........... I’m confused.
The type of numbers, rational and irrational from the numbers Keisha writes are;
a. Rational numbers; -9, 3.0, 2, and 2.42
b. Irrational numbers; √8
<h3>What is the difference between rational and irrational numbers?</h3>
Rational numbers are numbers are numbers that can be expressed as a ratio of two whole numbers P/Q, in which, <em>Q </em>≠ 0
Irrational numbers are those that cannot be expressed as a fraction P/Q
The given numbers are;
-9, √8, 3.0, 2, 2.42
- √8 = 2•√2 (√2 cannot be expressed as a fraction of two whole numbers)
a. The rational numbers are therefore;
b. The irrational number is; √8
