Answer:f(x)= -8 (4x) will be the reflected function across x-axis for the function g(x).
Explanation: since we know that the image or reflection of x along x-axis = -x
That is, when we talk about a function's reflection across any axis then we have to replace variable according to that axis. For example if you have a line x=3 in positive x-axis then you can also draw a similar line x=-3 in negative x-axis. so, you can say, x=-3 is the reflection of x=3 along x axis.
Similarly, for an another line y=3, y=-3 is a reflection.
thus in the case of g(x) we can find the reflection across x-axis after replacing x by -x.
we have g(x) =8(4x)
replace x by -x we get g(-x)= 8(4×-x)= 8(-4x)=-8(4x)
so -8(4x) is the reflection of g(x)
but according to the question f(x) is the reflection of g(x) across x-axis.
Thus, f(x)=-8(4x)
<h2>Answer:</h2><h2>Area of the kite = 80 
, Area of traingle = 40 and height of the triangle, h = 5 cm</h2>
Step-by-step explanation:
A kite is broken into two triangles
Given the base of the traingle, b = 16 cm
Height of the triangle, h = 5 cm
Area of traingle =
=
= 40
Area of the kite = area of triangle 1 + area of triangle 2
= 40 + 40
= 80
