Math Problem Statement

Differentiate the following function with respect to x: y = e^(5x^2 + 3x - 7)

Solution

The function you provided is:

y=e5x2+3x7y = e^{5x^2 + 3x - 7}

We are tasked with differentiating this function with respect to xx.

Step-by-step solution:

  1. Recognize the chain rule: Since the function is of the form y=eu(x)y = e^{u(x)}, where u(x)=5x2+3x7u(x) = 5x^2 + 3x - 7, we apply the chain rule. The derivative of eu(x)e^{u(x)} is eu(x)dudxe^{u(x)} \cdot \frac{du}{dx}.

  2. Differentiate u(x)=5x2+3x7u(x) = 5x^2 + 3x - 7: dudx=ddx(5x2)+ddx(3x)+ddx(7)\frac{du}{dx} = \frac{d}{dx}(5x^2) + \frac{d}{dx}(3x) + \frac{d}{dx}(-7) dudx=10x+3\frac{du}{dx} = 10x + 3

  3. Apply the chain rule: Now, the derivative of yy is: dydx=e5x2+3x7(10x+3)\frac{dy}{dx} = e^{5x^2 + 3x - 7} \cdot (10x + 3)

Thus, the derivative of the function is:

dydx=e5x2+3x7(10x+3)\frac{dy}{dx} = e^{5x^2 + 3x - 7} \cdot (10x + 3)

  5. What is the importance of exponential functions in calculus?

Tip: The chain rule is a powerful tool in differentiation. Practice applying it to various composite functions to build your intuition.
