Question:
What is the solution set for the equation below?

(Look a the image, and the multiple choices are there)

option (c)  is the correct answer.

Step-by-step explanation:

The given Quadratic equation is:

Let us try to make factors:

Here, can be written as (Look at the coefficient of and constant part i.e. 3 and 4). So, the quadratic equation becomes:

So, solution set for the equation is:

Hence, option (c)  is the correct answer.

The correct option is;

g(x) = Negative two-fifths(10)x

Step-by-step explanation:

The rule for the reflection across the x-axis is as follows;

Reflection about the x-axis

Pre-image point before reflection = (x, y)

Point of image after reflection = ((x, -y)

Therefore, the x coordinate remains the same while the y coordinate changes sign

For which given that f(x) = y = 2/5(10)x and g(x) = Reflection of f(x) across the x-axis, we have

Reflection about the x-axis

Pre-image point before reflection = (x, f(x))

Point of image after reflection = (x, g(x))

Hence g(x) = -f(x) = -2/5(10)x.
