for part a what happens to the +4 when u differentiate it?
Coefficients disappear when you diffrententiate them
ohh ok thanks
Actually a constant term rather than a coefficient, since the +4 does not come with any x attached.
To the OP, when a constant term gets differentiated, it becomes zero and effectively vanishes. The power of x in a constant term is counted as zero (here’s it’s 4 multiplied by x^0). When we differentiate, the “0” is moved down from the power, and this “0” will cause the entire expression 0 multiplied by 4 multiplied by x^(-1) to become zero.
