Answer:
-2x³+4x
Step-by-step explanation:
g(x) + f(x)
(2x) + (-2x³+2x)
-2x³+4x
Answer:
see the explanation
Step-by-step explanation:
we have

Find the inverse of A(x)
Let
y=A(x)

Exchange the variables x for y and y for x

Isolate the variable y


Let

------> function inverse of A(x)
<em>Explanation</em>
For x=1
Find the value of A(x)

The point (1,7) is a solution for A(x)
That means-----> The point (7,1) is a solution for the function inverse g(x)
Verify
For x=7
The point (7,1) is a solution for g(x)
therefore
A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)
1. y axis can repeat/x cannot repeat
2. Parabola symmetrically across y-axis
