Q. Exercises 15−28 15-28 , find the deri limit process.\newline1515. f(x)=7 f(x)=7 \newline1717. f(x)=−5x f(x)=-5 x
  1. Identify function: Identify the function to differentiate for exercise 1515.\newlinef(x)=7f(x) = 7
  2. Differentiate constant function: Differentiate the constant function f(x)=7f(x) = 7. The derivative of a constant is 00.
  3. Write final answer: Write the final answer for exercise 1515.\newlineThe derivative of f(x)=7f(x) = 7 is 00.
  4. Identify function: Identify the function to differentiate for exercise 1717.f(x)=−5xf(x) = -5x
  5. Differentiate linear function: Differentiate the linear function f(x)=−5xf(x) = -5x.\newlineThe derivative of −5x-5x with respect to xx is −5-5.
  6. Write final answer: Write the final answer for exercise 1717. The derivative of f(x)=−5xf(x) = -5x is −5-5.
