Identify Function: Identify the function to differentiate. The function given is a quotient of two functions, which means we will use the quotient rule to find the derivative. The quotient rule states that the derivative of a function h(x)=g(x)f(x) is given by h′(x)=(g(x))2g(x)f′(x)−f(x)g′(x).
Differentiate Numerator and Denominator: Differentiate the numerator and the denominator separately. The numerator is 2x2+x−3, and its derivative is 4x+1. The denominator is 2x+7, and its derivative is 2.
Apply Quotient Rule: Apply the quotient rule. Using the derivatives from Step 2, we have:h′(x)=(2x+7)2(2x+7)(4x+1)−(2x2+x−3)(2).
Expand Numerator: Expand the numerator of the derivative. We need to distribute the terms:(2x+7)(4x+1)=8x2+2x+28x+7=8x2+30x+7,(2x2+x−3)(2)=4x2+2x−6.Now subtract the second product from the first:(8x2+30x+7)−(4x2+2x−6)=8x2+30x+7−4x2−2x+6=4x2+28x+13.
Write Simplified Derivative: Write the derivative in its simplified form. The derivative is: h′(x)=(2x+7)24x2+28x+13.
Check Simplified Form: Check if the derivative is in the simplest form and if it answers the question prompt. The derivative is simplified, and it is the answer to the question prompt.
