1. Find the minimum and maximum values for the function with the given domain interval.
[tex]\[ k(x) = 10^x, \quad \text{for} \quad -3 \leq x \leq 1 \][/tex]

A. Minimum value: [tex]\(-3\)[/tex]; Maximum value: [tex]\(1\)[/tex]

B. Minimum value: None; Maximum value: None

C. Minimum value: [tex]\(0.1\)[/tex]; Maximum value: [tex]\(1,000\)[/tex]

D. Minimum value: [tex]\(0.001\)[/tex]; Maximum value: [tex]\(10\)[/tex]



Answer :

To find the minimum and maximum values for the function [tex]\( k(x) = 10^x \)[/tex] within the given domain interval [tex]\([-3, 1]\)[/tex], we need to evaluate the function at the endpoints of the interval.

1. Identify the endpoints of the interval:
- The minimum value in the domain is [tex]\( x = -3 \)[/tex].
- The maximum value in the domain is [tex]\( x = 1 \)[/tex].

2. Evaluate the function at these points:
- For [tex]\( x = -3 \)[/tex]:
[tex]\[ k(-3) = 10^{-3} = \frac{1}{10^3} = \frac{1}{1000} = 0.001 \][/tex]
- For [tex]\( x = 1 \)[/tex]:
[tex]\[ k(1) = 10^1 = 10 \][/tex]

3. Determine the minimum and maximum values:
- The function attains its minimum value at [tex]\( x = -3 \)[/tex], which is
[tex]\[ k(-3) = 0.001 \][/tex]
- The function attains its maximum value at [tex]\( x = 1 \)[/tex], which is
[tex]\[ k(1) = 10 \][/tex]

Therefore, the minimum value of the function [tex]\( k(x) \)[/tex] over the given interval is [tex]\( 0.001 \)[/tex] and the maximum value is [tex]\( 10 \)[/tex].

Hence, the correct answer is:
- Minimum value [tex]\( = 0.001 \)[/tex]
- Maximum value [tex]\( = 10 \)[/tex]

So, the answer is:
[tex]\[ \boxed{\text{minimum value } = 0.001 \text{; maximum value } = 10} \][/tex]
