let f(x) be a function that satisfies -3x^2 + 12x + 81 <= f(x) <= 3x^2 - 12x + 105 for all 0 <= x <= 3
a. what can you say about limit of f(x) as x approaches 0 to the right?

what is the correct statement?
we can evaluate the limit by substituting x = 0 into the lower bound for f(x)
we can evaluate the limit by substituting x = 0 into the upper bound for f(x)
we can evaluate the limit by substituting x = 0 into either the lower or upper bound for f(x)
there is insufficient information to determine its exact value

To solve this, we use the **Squeeze Theorem**, which states that if a function \( f(x) \) is squeezed between two functions and they both converge to the same limit as \( x \) approaches a point, then \( f(x) \) must also converge to that same limit.

The given inequalities are:
\[
-3x^2 + 12x + 81 \leq f(x) \leq 3x^2 - 12x + 105 \quad \text{for all} \quad 0 \leq x \leq 3
\]
### Step 1: Evaluate the lower bound as \( x \to 0^+ \):
\[
\lim_{x \to 0^+} \left( -3x^2 + 12x + 81 \right) = -3(0)^2 + 12(0) + 81 = 81
\]

### Step 2: Evaluate the upper bound as \( x \to 0^+ \):
\[
\lim_{x \to 0^+} \left( 3x^2 - 12x + 105 \right) = 3(0)^2 - 12(0) + 105 = 105
\]

### Step 3: Apply the Squeeze Theorem
As \( x \to 0^+ \), we have:
\[
81 \leq f(x) \leq 105
\]
Since the lower and upper bounds give different limits (81 and 105), the function \( f(x) \) is bounded but does not converge to a single value as \( x \to 0^+ \).

### Conclusion:
There is **insufficient information to determine its exact value** because the function is squeezed between two values that do not converge to the same limit.

So, the correct statement is:
- **There is insufficient information to determine its exact value.**
