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.

Answer:
Would it be 70/100 as a fraction and 0.7 as a decimal and 70% as a percentage?
Step-by-step explanation:
If you have 100 squares and 70 of those squares are shaded, your answer would 70/100.
You divide 91/14 to get w=6.5.
Answer:
x + 3 + 
Step-by-step explanation:
Divide using Synthetic division
dividing by ( x - 3)
Using 0 to represent the x- term
3 | 1 0 4
↓ 3 9
+ +
------------------
1 3 13 ← remainder
Thus
= x + 3 +
