2x² + 6x - 3 + 2x³ - 3x + 2
Combine like terms
2x³ + 2x² + 6x - 3x - 3 + 2
Final answer:
2x³ + 2x² + 3x - 1
Simple..
there is a major difference between 6z and

6z means: 6 times z
and

means: z to the power of 6(z*z*z*z*z*z)
An example...
make z=2...plug n chug..
6z----> 6(2)=12
and

--->

=64
As you can see..there is a
major difference.
Thus, your answer.
20 I apologize if this is wrong
Parent Function: f(x) = x^2
Right 2 units: f(x) = (x^2 - 2)
Down 4 units: f(x) = (x^2 - 2) - 4
Reflection over x-axis: f(x) = - (x^2 -2) + 4
Answer: f(x) = - (x^2 -2) + 4
