I think right is correct ( - 1, 5 )
When you are doing derivatives, you don't want to do it right away because there is still ( ) we need to remove that first get,
g(x)=3x^4-6x
Now we can do the derivatives!
g(x)=12*x^3 - 6
I hope this helps!
Let's say the point is C, and divides AB on a 4:7 ratio, from A to B, meaning the AC segment takes 4 units of the lot and the CB segment takes 7.

Answer:
Step-by-step explanation:
Pythagorean theorem
a² = 5² - 3² = 16
a = √16 = 4
