Math Problem Statement
find f(10), f(-1), f(16), f(-3), f(0)
Solution
Let's evaluate the piecewise function for the given values of .
The function is defined as:
3 + x & \text{if } -3 \leq x < 0 \\ 3 & \text{if } x = 0 \\ \sqrt{x} & \text{if } x > 0 \end{cases}$$ Now, let's find $$f(10)$$, $$f(-1)$$, $$f(16)$$, $$f(-3)$$, and $$f(0)$$: 1. **$$f(10)$$:** Since $$10 > 0$$, we use $$f(x) = \sqrt{x}$$. $$f(10) = \sqrt{10} \approx 3.16$$ 2. **$$f(-1)$$:** Since $$-1$$ falls in the interval $$-3 \leq x < 0$$, we use $$f(x) = 3 + x$$. $$f(-1) = 3 + (-1) = 2$$ 3. **$$f(16)$$:** Since $$16 > 0$$, we use $$f(x) = \sqrt{x}$$. $$f(16) = \sqrt{16} = 4$$ 4. **$$f(-3)$$:** Since $$-3$$ is exactly at the lower boundary of the interval $$-3 \leq x < 0$$, we use $$f(x) = 3 + x$$. $$f(-3) = 3 + (-3) = 0$$ 5. **$$f(0)$$:** Since $$x = 0$$, we use the corresponding rule, $$f(x) = 3$$. $$f(0) = 3$$ ### Final Answers: - $$f(10) = \sqrt{10} \approx 3.16$$ - $$f(-1) = 2$$ - $$f(16) = 4$$ - $$f(-3) = 0$$ - $$f(0) = 3$$ Would you like more details or have any other questions?
