Question

select the function f(x)=\sqrt{x + 4} and check the show values box. use the x - slide to aid in completing parts 1 through 3 below. use the interactive figure to find your answer. use the left and right arrow keys to move along a slider as needed. click here to launch the interactive figure. part 1: find the value of f(0). select the correct choice below and, if necessary, fill in the answer box to complete your choice. \bigcirc a. f(0)=\square \bigcirc b. f(0) has no value

Explanation:

Step1: Substitute x=0 into f(x)

$f(0) = \sqrt{0 + 4}$

Step2: Simplify the expression inside root

$f(0) = \sqrt{4}$

Step3: Calculate the square root

$f(0) = 2$

Answer:

A. $f(0)=2$
