Q. For the following equation, find f′(x).f(x)=8x3+5x+4Answer: f′(x)=
Differentiate 8x3: We will differentiate each term of the function separately.First, differentiate the term 8x3. Using the power rule, the derivative of 8x3 with respect to x is 3⋅8⋅x3−1=24x2.
Differentiate 5x: Next, differentiate the term 5x. The derivative of 5x with respect to x is 5, since the power of x is 1 and 1×x1−1=1×x0=1.
Differentiate constant 4: Finally, differentiate the constant term 4. The derivative of a constant with respect to x is 0, since constants do not change as x changes.
Combine derivatives: Now, we combine the derivatives of all the terms to get the derivative of the entire function f(x).f′(x)=24x2+5+0
Simplify expression: We can simplify the expression by removing the 0, as adding 0 does not change the value.f′(x)=24x2+5This is the fully simplified form of the derivative of the function f(x).
