Just remember that derivative of any constant is Zero.
In other words the value of 2 is always be 2 and therefore its is a fixed value.
But value of a number that we don't know such as X, Y,Z
etc is known as varible. which means that "X" can be 1 or 165494981094951561216948 some huge number.
Hope this helps.

The derivative of a constant is zero.
Hence ans= 0.
To understand this: derivative is the slope of the graph of the given function. The function y=-4 when ploted on a graph would give a straight line parallel to the x-axis.
Slope of any line parallel to the x-axis is zero.
Hence the slope of any function of the form y=k (any constant is zero)

You take the derivative of each side:
the derivative of y is dy/dt,
the derivative of a constant such as -4 is 0.
dy/dt=0.

Here y is variable but – 4 is not a a variable, is constant so derivative is zero.

The derivative of a constant is zero. remember this it is important for integration

not only y=-4 y=any constant equals 0

Deravative of any constant is zero.
so y=-4 deravative will be dy/dx=0.

y=-4^1
y=(1)*-4^1-1
y=(0)*-4^0
y=ZERO
