the graphs of the functions f(x) and g(x) are given in blue and red, respectively. suppose that u(x)=f(x)g(x) and v(x)=f(x)/g(x). find each of the following: u'(1) and v'(1).

Let's analyze the graphs of the two functions \( f(x) \) (blue) and \( g(x) \) (red) to find the values of \( u'(1) \) and \( v'(1) \).

Given:
- \( u(x) = f(x) \cdot g(x) \)
- \( v(x) = \frac{f(x)}{g(x)} \)

We need to use the product rule for \( u'(x) \) and the quotient rule for \( v'(x) \) at \( x = 1 \).

### 1. Find \( u'(x) \):
Using the product rule:
\[
u'(x) = f'(x)g(x) + f(x)g'(x)
\]
We will need \( f(1) \), \( f'(1) \), \( g(1) \), and \( g'(1) \).

### 2. Find \( v'(x) \):
Using the quotient rule:
\[
v'(x) = \frac{f'(x)g(x) - f(x)g'(x)}{g(x)^2}
\]

### Step 1: Derivatives and Function Values at \( x = 1 \)

From the graph:
- \( f(1) = 0 \) (since the blue graph passes through \( (1, 0) \)).
- \( g(1) = 0 \) (since the red graph also passes through \( (1, 0) \)).

#### Slopes:
- \( f'(1) \) is the slope of the blue line at \( x = 1 \), which is approximately \( 1 \) (from \( (0, 1) \) to \( (1, 0) \)).
- \( g'(1) \) is the slope of the red line at \( x = 1 \), which appears to be around \( 2 \) (based on the nearby points \( (0, -2) \) and \( (1, 0) \)).

### Step 2: Compute \( u'(1) \)
Substituting into the product rule:
\[
u'(1) = f'(1) \cdot g(1) + f(1) \cdot g'(1)
\]
\[
u'(1) = 1 \cdot 0 + 0 \cdot 2 = 0
\]

### Step 3: Compute \( v'(1) \)
Substituting into the quotient rule:
\[
v'(1) = \frac{f'(1)g(1) - f(1)g'(1)}{g(1)^2}
\]
\[
v'(1) = \frac{1 \cdot 0 - 0 \cdot 2}{0^2}
\]
This expression is undefined because of division by zero. Therefore, \( v'(1) \) is undefined.

### Final Answer:
- \( u'(1) = 0 \)
- \( v'(1) \) is undefined due to division by zero.
