Answer: The correct option is second.
Explanation:
The given function is,
If we graph a function is f(x), then its coordinates is defined as (x,f(x)).
When the graph of f(x) is reflect across the x-axis, then the the x-coordinate remains the same and the sign of y-coordinate is changed. It means after reflecting across the x-axis,
The given given equation can be written as,
To find the equation of the graph after reflection across the x-axis multiply both sides by -1.
Because f(x)=y and g(x)=-y.
Therefore the second option is correct and the graph of both function is given below.
Simplify the expression
6² + 9²
6² = 6 x 6 = 36
9² = 9 x 9 = 81
36 + 81 = 117
117 is a rational number ∴ <span>6</span>²<span> plus 9</span>² is rational
hope this helps
Answer:
A, B, and D.
Step-by-step explanation:
HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:
5^2 = 5 x 5
aka, 25.
You can use this to check each of the answers in your formula, like this:
if x=6, then:
x^2 < 100
6 x 6 = 36
36 < 100
A is one of your correct answers!
Also remember, if you multiply a negative by a negative, it becomes positive.
-5 x -5 = 25
-10 x -10 = 100
