Answer:
D
Step-by-step explanation:
you reverse the numbers in the y spot, so if they are negative make them positive, vise versa
Given:
To find:
The function .
Solution:
we have,
Put g(x)=y.
Interchange x and y.
Isolate y.
Substitute .
Therefore, the correct option is (3).
First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)
4x4x4=64 so its volume is 64
