Answer: Derivative of f(x) =3x+5=3
Step-by-step explanation:
By the Sum Rule, the derivative of 3x+5 with respect to x is d/dx[3x]+d/dx[5]
d/dx[3x]+d/dx[5]
evaluate: d/dx[3x]
Since 3 is constant with respect to x, the derivative of 3x with respect to x is 3d/dx[x].
3d/dx[x]+d/dx[5]
Differentiate using the power rule
which states that d/dx[[tex]x^{n}[/tex]] is [tex]nx^{n-1}[/tex] where n=1.
3⋅1+d/dx[5]
Multiply 3 by 1.
3+d/dx[5]
Differentiate using the Constant Rule.
Since 5 is constant with respect to x, the derivative of 5 with respect to x is 0.
3+0
Add 3 and 0 = 3
So, derivative of f(x) =3x+5=3
