Actually Welcome to the Concept of the derivatives.
Hence, y = 3 sin(-4x), we use the chain rule here.
dy/dx =3 ( cos(-4x).-4)
====> dy/dx = -12 cos(-4x)
Answer:
for example, if f(x)= x^2 + 3
and they gave write f(5)= 5^2 +3
=25+3=28
If 9kg costs 12$, then a single kg costs around 1.3$
This is done with a simple proportion
9 : 12 = 1 : X
x = 12/9
x = 1.33
2(x +4)-6(q/9)
The slash represents a division sign.
