Question

Evaluate the function $$ f(r)=\sqrt{r+8}+1 $$ at the given ve $$ \begin{array}{lll}	ext { a. } f(-8) & 	ext { b. } f(8) & 	ext { c. } f(x-8)\end{array} $$

UpStudy AI · Accepted Answer

Let's evaluate the function $$ f(r) = \sqrt{r + 8} + 1 $$ at the specified values:

### a. $$ f(-8) $$

$$
f(-8) = \sqrt{(-8) + 8} + 1 = \sqrt{0} + 1 = 0 + 1 = 1
$$

### b. $$ f(8) $$

$$
f(8) = \sqrt{8 + 8} + 1 = \sqrt{16} + 1 = 4 + 1 = 5
$$

### c. $$ f(x - 8) $$

$$
f(x - 8) = \sqrt{(x - 8) + 8} + 1 = \sqrt{x} + 1
$$

**Summary of Results:**

- **a.** $$ f(-8) = 1 $$
- **b.** $$ f(8) = 5 $$
- **c.** $$ f(x - 8) = \sqrt{x} + 1 $$
- **a.** $$ f(-8) = 1 $$ - **b.** $$ f(8) = 5 $$ - **c.** $$ f(x - 8) = \sqrt{x} + 1 $$

Evaluate the function \( f(r)=\sqrt{r+8}+1 \) at the given ve \( \begin{array}{lll}\text { a. } f(-8) & \text { b. } f(8) & \text { c. } f(x-8)\end{array} \)
