Question

Which of the following functions is graphed below?

Answer 1

The closed dot indicates that an "equal to" in the comparison is required, and on the other dot it is open, so this requirement is not needed, so this equation is the answer

Answer 2

D) f(x) = x^2 - 4 ; x > 1

x^2 _3, x ≤ 1

Explanation:

From the given graph, the graph of the function f(x) = x^2 - 4 start from x > 1.

The unfilled represents the open interval. Therefore, the domain of the function is (1, infinity), which represented by x > 1.

The graph of the function x^2 + 3, start from x ≤ 1.

The filled circle dot represents the closed interval. Therefore, the domain of the function is [1, -infinity) which represented by x ≤ 1

Therefore, the answer is D)

f(x) = x^2 - 4 ; x > 1

x^2 _3, x ≤ 1
