Answer:
The derivative of the function is 42.
Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0. The derivative of 3 is 0, for example.
The derivative of [tex]a*x^{n}[/tex] is [tex]a*n*x^{n-1}[/tex]. The derivative of 42x is 42, for example.
So, in this question, we have that:
h(x) = 42x-3
h'(x) = 42
So the derivative of the function is 42.
