Here is a table of values for [tex]\( y = f(x) \)[/tex].

[tex]\[
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}
\hline
$x$ & -5 & -3 & 0 & 2 & 6 & 7 & 9 & 10 & 13 \\
\hline
$f(x)$ & 1 & 2 & 3 & 0 & 1 & 2 & 3 & 0 & 1 \\
\hline
\end{tabular}
\][/tex]

Mark the statements that are true.

A. [tex]\( f(0) = 10 \)[/tex]

B. The range for [tex]\( f(x) \)[/tex] is all real numbers.

C. The domain for [tex]\( f(x) \)[/tex] is the set [tex]\(\{-5, -3, 0, 2, 6, 7, 9, 10, 13\}\)[/tex].

D. [tex]\( f(-3) = 2 \)[/tex]


Sagot :

Let's analyze each statement using the given table of values for [tex]\( f(x) \)[/tex] step-by-step.

### Statement A: [tex]\( f(0) = 10 \)[/tex]

First, we look at the table to find the value of [tex]\( f(x) \)[/tex] when [tex]\( x = 0 \)[/tex].
- According to the table, when [tex]\( x = 0 \)[/tex], [tex]\( f(0) = 3 \)[/tex].

Therefore, the statement [tex]\( f(0) = 10 \)[/tex] is false.

### Statement B: The range for [tex]\( f(x) \)[/tex] is all real numbers

To determine if this statement is true, we need to look at the range of values [tex]\( f(x) \)[/tex] takes in the table:
- The table shows that [tex]\( f(x) \)[/tex] takes on the values {1, 2, 3, 0}.

The range of [tex]\( f(x) \)[/tex] is {0, 1, 2, 3}. This set does not include all real numbers.

Therefore, the statement that the range for [tex]\( f(x) \)[/tex] is all real numbers is false.

### Statement C: The domain for [tex]\( f(x) \)[/tex] is the set [tex]\(\{-5, -3, 0, 2, 6, 7, 9, 10, 13\}\)[/tex]

To verify this, we need to check the [tex]\( x \)[/tex]-values provided in the table. The [tex]\( x \)[/tex]-values given are:
- {-5, -3, 0, 2, 6, 7, 9, 10, 13}

These values match exactly with the set described in the statement.

Therefore, the statement that the domain for [tex]\( f(x) \)[/tex] is the set [tex]\(\{-5, -3, 0, 2, 6, 7, 9, 10, 13\}\)[/tex] is true.

### Statement D: [tex]\( f(-3) = 2 \)[/tex]

Next, we check the value of [tex]\( f(x) \)[/tex] when [tex]\( x = -3 \)[/tex] from the table:
- According to the table, when [tex]\( x = -3 \)[/tex], [tex]\( f(-3) = 2 \)[/tex].

Therefore, the statement [tex]\( f(-3) = 2 \)[/tex] is true.

### Conclusion

Putting this all together:
- Statement A: False
- Statement B: False
- Statement C: True
- Statement D: True

Thus, the correct markings for the statements are:
- A. False
- B. False
- C. True
- D. True
