Answer:
140
Step-by-step explanation:
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:

Step-by-step explanation:

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

Substitute in the values of a, b, and c.

Answer:
x = 0; x = 5
Step-by-step explanation:
2x² = 10x
2x² - 10x = 0
2x(x - 5) = 0
x = 0; x = 5
