Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
Attached you will find the graph of g(x) (blue) and f(x) (red),
When leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
<h3>What is a Polynomial Function ?</h3>Functions of independent variable in which the variable can appear more than once with different powers.
Let this represents the polynomial function
where
Then the according to rational root theorem ,
The root of the function is given by
So when leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
