Let's start with problem 32 and 36 from the image.

Problem 32:

$f(x) = -x^2 + 3x + 2$

We are tasked with finding the derivative $f'(x)$, and then calculating $f'(1)$, $f'(2)$, and $f'(3)$.

Step 1: Find the derivative

To differentiate $f(x) = -x^2 + 3x + 2$, we apply the power rule for each term:

• The derivative of $-x^2$ is $-2x$
• The derivative of $3x$ is $3$
• The derivative of the constant $2$ is $0$

Thus, the derivative is: $f'(x) = -2x + 3$

Step 2: Calculate $f'(1)$, $f'(2)$, and $f'(3)$

1. $f'(1) = -2(1) + 3 = -2 + 3 = 1$
2. $f'(2) = -2(2) + 3 = -4 + 3 = -1$
3. $f'(3) = -2(3) + 3 = -6 + 3 = -3$

Problem 36:

$f(x) = \frac{6}{x} - 2$

Step 1: Find the derivative

To differentiate $f(x) = \frac{6}{x} - 2$, we rewrite the term $\frac{6}{x}$ as $6x^{-1}$:

• The derivative of $6x^{-1}$ using the power rule is $-6x^{-2}$, which simplifies to $-\frac{6}{x^2}$
• The derivative of $-2$ is $0$

Thus, the derivative is: $f'(x) = -\frac{6}{x^2}$

Step 2: Calculate $f'(1)$, $f'(2)$, and $f'(3)$

1. $f'(1) = -\frac{6}{1^2} = -6$
2. $f'(2) = -\frac{6}{2^2} = -\frac{6}{4} = -\frac{3}{2}$
3. $f'(3) = -\frac{6}{3^2} = -\frac{6}{9} = -\frac{2}{3}$

Summary of Results:

• Problem 32:

  • $f'(x) = -2x + 3$
  • $f'(1) = 1$
  • $f'(2) = -1$
  • $f'(3) = -3$

• Problem 36:

  • $f'(x) = -\frac{6}{x^2}$
  • $f'(1) = -6$
  • $f'(2) = -\frac{3}{2}$
  • $f'(3) = -\frac{2}{3}$
