Apply rules for differentiation: Apply the constant multiple rule and the sum rule for differentiation.The constant multiple rule states that the derivative of a constant times a function is the constant times the derivative of the function. The sum rule states that the derivative of a sum of functions is the sum of their derivatives.So, we will differentiate the function 2(x2+4) by applying these rules.f(x)=2(x2+4)f′(x)=2⋅dxd(x2)+2⋅dxd(4)
Differentiate individual terms: Differentiate the individual terms.The derivative of x2 with respect to x is 2x, using the power rule which states that dxd(xn)=n⋅x(n−1).The derivative of a constant, like 4, is 0.So, we have:f′(x)=2⋅(2x)+2⋅0
Simplify the expression: Simplify the expression.Now we simplify the expression by multiplying the constants and adding up the terms.f′(x)=4x+0f′(x)=4x
