Which of the following functions is graphed below?

The graph consists of two parts: left part (with sign < or ≤) - parabola and right part (with sign > or ≥) - straight line.

Determine signs:

From the diagram you can see that the right endpoint (4,19)  of parabola is not included. This means that x cannot be equal to 4 at this part of graph and the sign should be <.

Also you can see that the left endpoint (4,8)  of line is included. This means that x=4 belongs to the right part and the sign should be ≥.

Using previous conclusions, you can state that correct choice is D.

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
