Question

Обчисліть f(-3), якщо f(x) =√х²+16​

Answer 1

Ответ:

19

Объяснение:

f(-3) = √(-3)²+16 = |-3|+16 = 19

Answer 2

I can help you with math problems, among other things. To find f(-3), you need to substitute x with -3 in the given function. That is,

$$f(-3) = \sqrt{(-3)^2 + 16}$$

Then, you need to simplify the expression inside the square root. That is,

$$f(-3) = \sqrt{9 + 16}$$

Finally, you need to find the square root of the sum. That is,

$$f(-3) = \sqrt{25}$$

The answer is

$$f(-3) = 5$$

I hope this helps. If you have any other questions, feel free to ask me.Ответь+подробно.++Обчисліть+f(-3),+якщо+f(x)+=√х²+16​+
